==Main Idea==

Newton’s Third Law of Motion describes a push or pull that acts on an object as a result of its interaction with another object. According to this law for every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Meaning that when an object 1 pushes another object 2 then object 1 gets pushed back with equal force but in the opposite direction. [[File: Law3 f1.gif | thumb | left | 250px |If you push an object with 100N it will push back on you with equal but opposite force.]][[File: Snip20151127_7.png| thumb | right | 200px| Mathematically Formula to describe Newton's Third Law ]]

The third law of motion is also referred to as the action-reaction law because both objects are part of a single interaction and neither force can exist without the other. An important concept to remember about Newton's Third Law of Motion is that the two forces are of the same type. For example, when you throw a ball in the sky the Earth exerts a gravitational force on the ball and the ball also exerts a [[File: 924.gif | thumb | right | 250px | The canon pushes the canon ball forward and the canon pushes the canon back with equal force.]] gravitational force that is equal in magnitude and opposite in direction on the earth. Another example, that can sum up the concept of Newton's Third Law is when you walk. When you push down upon the ground and ground pushes with the same force upward. Similarly, the tires of a car push against the road while the road pushes back on the tires.

==Examples==

Here are some problems regarding Newton's Third Law.

===Simple===

==== Question ====

[[File: Snip20151128_10.png| thumb | left | 250px |Simple Example]]Car B is stopped at a red light. The brakes in Car A have failed and Car A is coming towards Car B at 60 kmh. Car B then runs into the back of Car A, What can be said about the force on Car A on Car B and the force on Car B on Car A?

==== Answer ====

B exerts the same amount of force on A as A exerts on B.
Just the direction of both the forces will be in the opposite direction.

===MIddle===

====Question====

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 8 N force applied to the 1 kg block. (a) How much force does the 2 kg block exert on the 3 kg block? (b) How much force does the 2 kg block exert on the 1 kg block?

====Answer====

(a)
Find the Acceleration of the Whole Object:
Total Mass: 6kg
8 = (6) a
a = 8 / 6 = 1.33 m/s^2
Total Acceleration: 1.33 m/s^2 (Acceleration will be the same for all three blocks)
F(2 on 3) = m(3) * a
3 * 1.33 = 3.999 N

(b)
Total Acceleration: 1.33 m/s^2
Mass to push: 5 kg (Because we are also pushing the 3 kg block)
F(1 on 2) = 5 * 1.33
F(1 on 2) = 5.33 N

===Difficult===

====Question====
A massive steel cable drags a 30 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 5.0 m/s in a distance of 5.0 m. What is the mass of the cable?

====Answer====

a = V² / (2x) = 2.5 m/s²
F = M * a → 100 = (30+m) * 2.5
m = 10 kg

#How is this topic connected to something that you are interested in?

Newton's Third Law is connected to the concept of a spacecraft flying in space. When a spacecraft
fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes
against the exhaust gas. The gas and rocket move in opposite directions. This is an
example of Newton's Third Law because both forces are equal in magnitude and opposite
in direction. This topic is related to space travel a topic that I am interested in and
passionate about learning more.

==History==

Sir Isaac Newton was a renowned scientist and mathematician who helped create a foundation for modern studies. He was born in England in 1643 and worked his way to earn a bachelor’s and master’s degree from Trinity College Cambridge. He was highly interested in math, physics, and astronomy and wrote many of his ideas in a journal. One of those ideas was about the three laws of motion. [[File: Sir_Isaac_Newton_(1643-1727).jpg| thumb | left | 150px| Sir Isaac Newton (1643 - 1727)]] In 1687 Isaac Newton made his work on his book, Philosophiae Naturalis Principia Mathematic or Principia known to the public. He discussed the principles of time, force, and motion that helped create modern physical science and helped account for much of the phenomena viewed in the world. Some of the principles he discusses include acceleration, initial movement, fluid dynamics, and motion. Newton’s Laws first appeared in the Principia and discussed the relationship that exists between forces acting on a body and the motion of the body. For the third law, he stated that for every action/force in nature, there will be an equal and opposite reaction.

==Main Idea==

Newton’s Third Law of Motion describes a push or pull that acts on an object as a result of its interaction with another object. According to this law for every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Meaning that when an object 1 pushes another object 2 then object 1 gets pushed back with equal force but in the opposite direction. [[File: Law3 f1.gif | thumb | left | 250px |If you push an object with 100N it will push back on you with equal but opposite force.]][[File: Snip20151127_7.png| thumb | right | 200px| Mathematically Formula to describe Newton's Third Law ]]

The third law of motion is also referred to as the action-reaction law because both objects are part of a single interaction and neither force can exist without the other. An important concept to remember about Newton's Third Law of Motion is that the two forces are of the same type. For example, when you throw a ball in the sky the Earth exerts a gravitational force on the ball and the ball also exerts a [[File: 924.gif | thumb | right | 250px | The canon pushes the canon ball forward and the canon pushes the canon back with equal force.]] gravitational force that is equal in magnitude and opposite in direction on the earth. Another example, that can sum up the concept of Newton's Third Law is when you walk. When you push down upon the ground and ground pushes with the same force upward. Similarly, the tires of a car push against the road while the road pushes back on the tires.

==Examples==

Here are some problems regarding Newton's Third Law.

===Simple===

==== Question ====

[[File: Snip20151128_10.png| thumb | left | 250px |Simple Example]]Car B is stopped at a red light. The brakes in Car A have failed and Car A is coming towards Car B at 60 kmh. Car B then runs into the back of Car A, What can be said about the force on Car A on Car B and the force on Car B on Car A?

==== Answer ====

B exerts the same amount of force on A as A exerts on B.
Just the direction of both the forces will be in the opposite direction.

===MIddle===

====Question====

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 8 N force applied to the 1 kg block. (a) How much force does the 2 kg block exert on the 3 kg block? (b) How much force does the 2 kg block exert on the 1 kg block?

====Answer====

(a)
Find the Acceleration of the Whole Object:
Total Mass: 6kg
8 = (6) a
a = 8 / 6 = 1.33 m/s^2
Total Acceleration: 1.33 m/s^2 (Acceleration will be the same for all three blocks)
F(2 on 3) = m(3) * a
3 * 1.33 = 3.999 N

(b)
Total Acceleration: 1.33 m/s^2
Mass to push: 5 kg (Because we are also pushing the 3 kg block)
F(1 on 2) = 5 * 1.33
F(1 on 2) = 5.33 N

===Difficult===

====Question====
A massive steel cable drags a 30 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 5.0 m/s in a distance of 5.0 m. What is the mass of the cable?

====Answer====

a = V² / (2x) = 2.5 m/s²
F = M * a → 100 = (30+m) * 2.5
m = 10 kg

Newton's Third Law is connected to the concept of a spacecraft flying in space. When a spacecraft
fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes against
the exhaust gas. The gas and rocket move in opposite directions. This is an example of Newton's
Third Law because both forces are equal in magnitude and opposite in direction. This topic is related

==History==

Sir Isaac Newton was a renowned scientist and mathematician who helped create a foundation for modern studies. He was born in England in 1643 and worked his way to earn a bachelor’s and master’s degree from Trinity College Cambridge. He was highly interested in math, physics, and astronomy and wrote many of his ideas in a journal. One of those ideas was about the three laws of motion. [[File: Sir_Isaac_Newton_(1643-1727).jpg| thumb | left | 150px| Sir Isaac Newton (1643 - 1727)]] In 1687 Isaac Newton made his work on his book, Philosophiae Naturalis Principia Mathematic or Principia known to the public. He discussed the principles of time, force, and motion that helped create modern physical science and helped account for much of the phenomena viewed in the world. Some of the principles he discusses include acceleration, initial movement, fluid dynamics, and motion. Newton’s Laws first appeared in the Principia and discussed the relationship that exists between forces acting on a body and the motion of the body. For the third law, he stated that for every action/force in nature, there will be an equal and opposite reaction.

==Main Idea==

Newton’s Third Law of Motion describes a push or pull that acts on an object as a result of its interaction with another object. According to this law for every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Meaning that when an object 1 pushes another object 2 then object 1 gets pushed back with equal force but in the opposite direction. [[File: Law3 f1.gif | thumb | left | 250px |If you push an object with 100N it will push back on you with equal but opposite force.]][[File: Snip20151127_7.png| thumb | right | 200px| Mathematically Formula to describe Newton's Third Law ]]

The third law of motion is also referred to as the action-reaction law because both objects are part of a single interaction and neither force can exist without the other. An important concept to remember about Newton's Third Law of Motion is that the two forces are of the same type. For example, when you throw a ball in the sky the Earth exerts a gravitational force on the ball and the ball also exerts a [[File: 924.gif | thumb | right | 250px | The canon pushes the canon ball forward and the canon pushes the canon back with equal force.]] gravitational force that is equal in magnitude and opposite in direction on the earth. Another example, that can sum up the concept of Newton's Third Law is when you walk. When you push down upon the ground and ground pushes with the same force upward. Similarly, the tires of a car push against the road while the road pushes back on the tires.

==Examples==

Here are some problems regarding Newton's Third Law.

===Simple===

==== Question ====

[[File: Snip20151128_10.png| thumb | left | 250px |Simple Example]]Car B is stopped at a red light. The brakes in Car A have failed and Car A is coming towards Car B at 60 kmh. Car B then runs into the back of Car A, What can be said about the force on Car A on Car B and the force on Car B on Car A?

==== Answer ====

B exerts the same amount of force on A as A exerts on B.
Just the direction of both the forces will be in the opposite direction.

===MIddle===

====Question====

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 8 N force applied to the 1 kg block. (a) How much force does the 2 kg block exert on the 3 kg block? (b) How much force does the 2 kg block exert on the 1 kg block?

====Answer====

(a)
Find the Acceleration of the Whole Object:
Total Mass: 6kg
8 = (6) a
a = 8 / 6 = 1.33 m/s^2
Total Acceleration: 1.33 m/s^2 (Acceleration will be the same for all three blocks)
F(2 on 3) = m(3) * a
3 * 1.33 = 3.999 N

(b)
Total Acceleration: 1.33 m/s^2
Mass to push: 5 kg (Because we are also pushing the 3 kg block)
F(1 on 2) = 5 * 1.33
F(1 on 2) = 5.33 N

===Difficult===

====Question====
A massive steel cable drags a 30 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 5.0 m/s in a distance of 5.0 m. What is the mass of the cable?

====Answer====

a = V² / (2x) = 2.5 m/s²
F = M * a → 100 = (30+m) * 2.5
m = 10 kg

==Connectedness==

#How is this topic connected to something that you are interested in?

Newton's Third Law is connected to the concept of a spacecraft flying in space. When a spacecraft
fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes against
the exhaust gas. The gas and rocket move in opposite directions. This is an example of Newton's
Third Law because both forces are equal in magnitude and opposite in direction. This topic is related
to space travel a topic that I am interested in and passionate about learning more.

==History==

Sir Isaac Newton was a renowned scientist and mathematician who helped create a foundation for modern studies. He was born in England in 1643 and worked his way to earn a bachelor’s and master’s degree from Trinity College Cambridge. [[File: Sir_Isaac_Newton_(1643-1727).jpg| thumb | right | 200px| Sir Isaac Newton (1643 - 1727)]]
He was highly interested in math, physics, and astronomy and wrote many of his ideas in a journal. One of those ideas was about the three laws of motion.

==Main Idea==

Newton’s Third Law of Motion describes a push or pull that acts on an object as a result of its interaction with another object. According to this law for every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Meaning that when an object 1 pushes another object 2 then object 1 gets pushed back with equal force but in the opposite direction. [[File: Law3 f1.gif | thumb | left | 250px |If you push an object with 100N it will push back on you with equal but opposite force.]][[File: Snip20151127_7.png| thumb | right | 200px| Mathematically Formula to describe Newton's Third Law ]]

The third law of motion is also referred to as the action-reaction law because both objects are part of a single interaction and neither force can exist without the other. An important concept to remember about Newton's Third Law of Motion is that the two forces are of the same type. For example, when you throw a ball in the sky the Earth exerts a gravitational force on the ball and the ball also exerts a [[File: 924.gif | thumb | right | 250px | The canon pushes the canon ball forward and the canon pushes the canon back with equal force.]] gravitational force that is equal in magnitude and opposite in direction on the earth. Another example, that can sum up the concept of Newton's Third Law is when you walk. When you push down upon the ground and ground pushes with the same force upward. Similarly, the tires of a car push against the road while the road pushes back on the tires.

==Examples==

Here are some problems regarding Newton's Third Law.

===Simple===

==== Question ====

[[File: Snip20151128_10.png| thumb | left | 250px |Simple Example]]Car B is stopped at a red light. The brakes in Car A have failed and Car A is coming towards Car B at 60 kmh. Car B then runs into the back of Car A, What can be said about the force on Car A on Car B and the force on Car B on Car A?

==== Answer ====

B exerts the same amount of force on A as A exerts on B.
Just the direction of both the forces will be in the opposite direction.

===MIddle===

====Question====

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 8 N force applied to the 1 kg block. (a) How much force does the 2 kg block exert on the 3 kg block? (b) How much force does the 2 kg block exert on the 1 kg block?

====Answer====

(a)
Find the Acceleration of the Whole Object:
Total Mass: 6kg
8 = (6) a
a = 8 / 6 = 1.33 m/s^2
Total Acceleration: 1.33 m/s^2 (Acceleration will be the same for all three blocks)
F(2 on 3) = m(3) * a
3 * 1.33 = 3.999 N

(b)
Total Acceleration: 1.33 m/s^2
Mass to push: 5 kg (Because we are also pushing the 3 kg block)
F(1 on 2) = 5 * 1.33
F(1 on 2) = 5.33 N

===Difficult===

====Question====
A massive steel cable drags a 30 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 5.0 m/s in a distance of 5.0 m. What is the mass of the cable?

====Answer====

a = V² / (2x) = 2.5 m/s²
F = M * a → 100 = (30+m) * 2.5
m = 10 kg

#How is this topic connected to something that you are interested in?

Newton's Third Law is connected to the concept of a spacecraft flying in space. When a spacecraft
fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes against
the exhaust gas. The gas and rocket move in opposite directions. This is an example of Newton's
Third Law because both forces are equal in magnitude and opposite in direction. This topic is related
to space travel a topic that I am interested in and passionate about learning more.

For example, when you throw a ball in the sky the Earth exerts a gravitational force on the ball and the ball also exerts a [[File: 924.gif | thumb | right | 250px | The canon pushes the canon ball forward and the canon pushes the canon back with equal force.]] gravitational force that is equal in magnitude and opposite in direction on the earth. Another example, that can sum up the concept of Newton's Third Law is when you walk. When you push down upon the ground and ground pushes with the same force upward. Similarly, the tires of a car push against the road while the road pushes back on the tires.

==Examples==

Here are some problems regarding Newton's Third Law.

===Simple===

==== Question ====

[[File: Snip20151128_10.png| thumb | left | 250px |Simple Example]]Car B is stopped at a red light. The brakes in Car A have failed and Car A is coming towards Car B at 60 kmh. Car B then runs into the back of Car A, What can be said about the force on Car A on Car B and the force on Car B on Car A?

==== Answer ====

B exerts the same amount of force on A as A exerts on B.
Just the direction of both the forces will be in the opposite direction.

===MIddle===

====Question====

Blocks with masses of 1 kg, 2 kg, and 3 kg are lined up in a row on a frictionless table. All three are pushed forward by a 8 N force applied to the 1 kg block. (a) How much force does the 2 kg block exert on the 3 kg block? (b) How much force does the 2 kg block exert on the 1 kg block?

====Answer====

(a)
Find the Acceleration of the Whole Object:
Total Mass: 6kg
8 = (6) a
a = 8 / 6 = 1.33 m/s^2
Total Acceleration: 1.33 m/s^2 (Acceleration will be the same for all three blocks)
F(2 on 3) = m(3) * a
3 * 1.33 = 3.999 N

(b)
Total Acceleration: 1.33 m/s^2
Mass to push: 5 kg (Because we are also pushing the 3 kg block)
F(1 on 2) = 5 * 1.33
F(1 on 2) = 5.33 N

===Difficult===

====Question====
A massive steel cable drags a 30 kg block across a horizontal, frictionless surface. A 100 N force applied to the cable causes the block to reach a speed of 5.0 m/s in a distance of 5.0 m. What is the mass of the cable?

====Answer====

a = V² / (2x) = 2.5 m/s²
F = M * a → 100 = (30+m) * 2.5
m = 10 kg

#How is this topic connected to something that you are interested in?

Newton's Third Law is connected to the concept of a spacecraft flying in space. When a spacecraft
fires a thruster rocket, the exhaust gas pushes against the thruster and the thruster pushes against
the exhaust gas. The gas and rocket move in opposite directions. This is an example of Newton's
Third Law because both forces are equal in magnitude and opposite in direction. This topic is related
to space travel a topic that I am interested in and passionate about learning more.

==Main Idea==

Newton’s Third Law of Motion describes a push or pull that acts on an object as a result of its interaction with another object. According to this law for every action there is an equal and opposite re-action. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Meaning that when an object 1 pushes another object 2 then object 1 gets pushed back with equal force but in the opposite direction. [[File: Law3 f1.gif | thumb | left | 250px |If you push an object with 100N it will push back on you with equal but opposite force.]][[File: Snip20151127_7.png| thumb | right | 200px| Mathematically Formula to describe Newton's Third Law ]]
