&lt;div&gt;An Exploration of Spring Potential Energy: Lanier Freeman and other&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
&lt;br /&gt;
Other:&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
Me: More specifically, it [potential energy] relates to one half the product of the spring constant and the change in length squared.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Lanier begins here and continues thru computational section:&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
&lt;br /&gt;
All Lanier&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Simple&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt;, what is its potential energy?&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = \frac{1}{2}(1000)(0.1)^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = 5\;J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Moderate&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt; by an unknown mass, find the unknown mass.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = k\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{k\Delta x}{g} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{(1000)(0.1)}{9.8} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m \approx 10.204\;kg &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Difficult&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If the total potential energy of a system consisting of a mass suspended on a spring is &amp;lt;math&amp;gt; 100\;J&amp;lt;/math&amp;gt;, the mass is two metres off the ground,  and the mass of the object is &amp;lt;math&amp;gt;4.081\;kg&amp;lt;/math&amp;gt;, find the spring potential energy.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \sum U = U_{g}+U_s &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-mgh &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-(4.081)(9.8)(2) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 20 J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Lanier&#039;s Answers&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
1. This topic is of much interest to me because of the applications of the mean value theorem of calculus to problems dealing with potential energy--both spring and gravitational. I think this type of problem underscores the amazing power of the MVT.&lt;br /&gt;
&lt;br /&gt;
2. This topic relates to being a math major for obvious reasons; it presents a basic, practical application for advanced mathematics, something that isn&#039;t seen often in my experience.&lt;br /&gt;
&lt;br /&gt;
3. A silly yet decent example of industrial applications of spring applications is the way many pens are constructed: A spring of specific dimensions requiring a spring constant within a certain range is necessary to make the button on a pen work.&lt;br /&gt;

&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Simple&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt;, what is its potential energy?&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = \frac{1}{2}(1000)(0.1)^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = 5\;J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Moderate&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt; by an unknown mass, find the unknown mass.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = k\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{k\Delta x}{g} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{(1000)(0.1)}{9.8} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m \approx 10.204\;kg &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Difficult&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If the total potential energy of a system consisting of a mass suspended on a spring is &amp;lt;math&amp;gt; 100\;J&amp;lt;/math&amp;gt;, the mass is two metres off the ground,  and the mass of the object is &amp;lt;math&amp;gt;4.081\;kg&amp;lt;/math&amp;gt;, find the spring potential energy.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \sum U = U_{g}+U_s &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-mgh &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-(4.081)(9.8)(2) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 20 J &amp;lt;/math&amp;gt;&lt;br /&gt;

#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;

&lt;div&gt;An Exploration of Spring Potential Energy: Lanier Freeman and other&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;

&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;

#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;

There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out.&lt;br /&gt;

&lt;div&gt;An Exploration of Spring Potential Energy: Lanier Freeman and other&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out.&lt;br /&gt;

**Lanier&#039;s Answers**&lt;br /&gt;
&lt;br /&gt;
1. This topic is of much interest to me because of the applications of the mean value theorem of calculus to problems dealing with potential energy--both spring and gravitational. I think this type of problem underscores the amazing power of the MVT.&lt;br /&gt;
&lt;br /&gt;
2. This topic relates to being a math major for obvious reasons; it presents a basic, practical application for advanced mathematics, something that isn&#039;t seen often in my experience.&lt;br /&gt;
&lt;br /&gt;
3. A silly yet decent example of industrial applications of spring applications is the way many pens are constructed: A spring of specific dimensions requiring a spring constant within a certain range is necessary to make the button on a pen work.&lt;br /&gt;

&lt;div&gt;Ideal Spring: Lanier Freeman&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Simple&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt;, what is its potential energy?&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = \frac{1}{2}(1000)(0.1)^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = 5\;J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Moderate&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt; by an unknown mass, find the unknown mass.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = k\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{k\Delta x}{g} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{(1000)(0.1)}{9.8} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m \approx 10.204\;kg &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Difficult&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If the total potential energy of a system consisting of a mass suspended on a spring is &amp;lt;math&amp;gt; 100\;J&amp;lt;/math&amp;gt;, the mass is two metres off the ground,  and the mass of the object is &amp;lt;math&amp;gt;4.081\;kg&amp;lt;/math&amp;gt;, find the spring potential energy.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \sum U = U_{g}+U_s &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-mgh &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-(4.081)(9.8)(2) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 20 J &amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;div&gt;Ideal Spring: Lanier Freeman&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Simple&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 \;cm &amp;lt;/math&amp;gt;, what is its potential energy?&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = \frac{1}{2}(1000)(0.1)^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = 5\;J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Moderate&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 \;N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; \;10 cm &amp;lt;/math&amp;gt; by an unknown mass, find the unknown mass.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = k\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{k\Delta x}{g} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{(1000)(0.1)}{9.8} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; m \approx 10.204\;kg &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Difficult&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If the total potential energy of a system consisting of a mass suspended on a spring is &amp;lt;math&amp;gt; 100\;J&amp;lt;/math&amp;gt;, the mass is two metres off the ground,  and the mass of the object is &amp;lt;math&amp;gt;4.081kg&amp;lt;/math&amp;gt;, find the spring potential energy.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \sum U = U_{g}+U_s &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-mgh &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 100-(4.081)(9.8)(2) &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_s = 20 J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out. &lt;br /&gt;
&lt;br /&gt;
==History==&lt;br /&gt;
&lt;br /&gt;

**The term potential energy was introduced e, although it has links to Greek philosopher Aristotle&#039;s concept of potentiality.&lt;br /&gt;
**Scottish engineer and physicist &lt;br /&gt;

&lt;br /&gt;
*&#039;&#039;&#039;Robert Hooke&#039;&#039;&#039;&lt;br /&gt;
**Came up with Hooke&#039;s Law, which is used to find the potential energy of springs.&lt;br /&gt;
**Coined the term &amp;quot;cell&amp;quot; in biology&lt;br /&gt;

==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out. &lt;br /&gt;

&lt;div&gt;Ideal Spring: Lanier Freeman&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot the change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Simple&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 cm &amp;lt;/math&amp;gt;, what is its potential energy?&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U = \frac{1}{2}(1000)(0.1)^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; U = 5 J &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Moderate&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;If a spring has a spring constant of &amp;lt;math&amp;gt; 1000 N/m &amp;lt;/math&amp;gt; and is stretched &amp;lt;math&amp;gt; 10 cm &amp;lt;/math&amp;gt; by an unknown mass, find the unknown mass.&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F = k\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{k\Delta x}{g} &amp;lt;/math&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt; m = \frac{(1000)(0.1)}{9.8} &amp;lt;/math&amp;gt;&lt;br /&gt;

#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;

&lt;div&gt;Ideal Spring: Lanier Freeman&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
===A mathematical evaluation===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ta-dah!&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot The change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the displacement squared and &amp;lt;math&amp;gt; \frac{k}{2} &amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;

*We then look at the definition of work and infer the following:&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;

===Computational Evaluation===&lt;br /&gt;
&lt;br /&gt;
When we plot The change in potential energy of a spring as a function of equilibrium displacement in vPython, we arrive at a parabolic model like the one in this image:&lt;br /&gt;
&lt;br /&gt;
[[File:Parabolicmodel.jpg]]&lt;br /&gt;
&lt;br /&gt;
Our independent variable is the displacement of the spring from its equilibrium position, and the dependent variable is the product of the square of this displacement and &amp;lt;math&amp;gt; \frac{k}{2}. &amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*We then look at the definition of work and infer the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = f\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Using the mean value theorem of integrals, we simplify the nonconstant force using the mean value theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}x \;dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\cdot \frac{\Delta x^2}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k\Delta x}{2} &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Finally, we arrive at the above formula for spring potential energy:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{k\Delta x}{2}\cdot \Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;

==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out. &lt;br /&gt;

&amp;lt;math&amp;gt; \Delta U_{spring} = \frac{1}{2}k\Delta x^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* derive this, consider the following from the work-energy theorem:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U_{spring} = W &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt; W = F\Delta x &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt; F_{avg} = \frac{k}{\Delta x}\int_{x_1}^{x_2}\Delta x dx &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
*The average value of &amp;lt;math&amp;gt; \Delta x &amp;lt;/math&amp;gt; over the range of interest is the following:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \bar{\Delta x} = \frac{1}{\Delta x}\int_{x_1}^{x_2}x\;dx &amp;lt;/math&amp;gt;&lt;br /&gt;

==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;
&lt;br /&gt;
#Is there an interesting industrial application?&lt;br /&gt;
There was an interesting industrial application where we can calculate the energy required by the machine to pump the fluid out. &lt;br /&gt;

&lt;div&gt;Ideal Spring: Lanier Freeman&lt;br /&gt;
&lt;br /&gt;
==The Key Concept==&lt;br /&gt;
Studying macroscopic springs pulls us out of the theoretical atomic realm and into the physical world of springs. The potential energy of a spring changes as the end of the coil varies in its relative distance from the location of its affixed base.&lt;br /&gt;
&lt;br /&gt;
==Terms and Definitions==&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Potential Energy&#039;&#039;&#039; - the energy stored in a body or system that results inherently from its relative position to another object&lt;br /&gt;
* A change in potential energy occurs when there is a change in the separation distance between the two objects.&lt;br /&gt;
* Gravitational potential energy relates the vertical position of an object to the surface of the Earth.&lt;br /&gt;
&amp;lt;math&amp;gt; \Delta U\approx \Delta mgy &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* With spring potential energy, we relate potential energy to one half the product of the spring constant and the square of equilibrium displacement, or this:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; U_{spring} = \frac{1}{2}kx^2 &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Connectedness==&lt;br /&gt;
#How is this topic connected to something that you are interested in?&lt;br /&gt;
This is the first law of thermodynamics where every energy related goes around with this law, where energy is neither made or destroyed. &lt;br /&gt;
It is very interesting how energy is just there and is transformed into other energies such as chemical energy that the food in the student center has will transform into kinetic energy when playing tennis after school. &lt;br /&gt;
 &lt;br /&gt;
#How is it connected to your major?&lt;br /&gt;
As my major is Chemical Engineering, thermodynamics has many materials in common because of calculating the energy balances toward a reaction. The first law of thermodynamics To work out thermodynamic problems you will need to isolate a certain portion of the universe, the system, from the remainder of the universe, the surroundings.&lt;br /&gt;

&amp;lt;div class=&amp;quot;mw-collapsible-content&amp;quot;&amp;gt;&lt;br /&gt;
*[[Node Rule]]&lt;br /&gt;
**In an electric circuit in series, electrons flow from the negative end of a power source, creating a constant current. This current remains consistent at each point in the circuit in series. Sometimes, a circuit is not simply one constant path and may include parts that are in parallel, where the current must travel down two paths such as this:&lt;br /&gt;
**[[File:noderule.jpg]] &lt;br /&gt;
**In this case, when the current enters a portion of the circuit where the items are in parallel, the total amount of current in must equal the total amount of current out. Therefore, the currents in each branch of the parallel portion must sum up to the amount of current at any other point in series in the circuit. &lt;br /&gt;
**For the previous image, the node rules can be written as I_total = I_1 + I_2 and I_total = I_3 + I_4. It is also true that I_1 + I_2 = I_3 + I_4. &lt;br /&gt;
**However, each of these currents are different because each point has a different resistance. The current is different for each because it is equal to V/R, and in a parallel circuit, the voltage drop across each point is equal. &lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
