[[File:Whatisvelocity.gif|thumb|alt=Definition|What is velocity?]]<br />
<br />
Velocity is the time rate of change of position of a body in a specified direction. It is a vector quantity that consists of a magnitude and direction. Speed is also the change of position of a body; however, it does not take the object's direction into consideration.<br />
<br />
==Equation==<br />
<br />
Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Example==<br />
<br />
[[File:Caronroad.jpg|thumb|alt=Example|3 hour, 230-mile trip]]<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />

|-<br />
|}<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
Given the example: Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities. It is important to note that as <math>{\Delta\mathit{t}}</math> gets very small, the average velocity approaches the instantaneous velocity. <br />
<br />
Given the example: The average velocity would be (230 miles/3 hours) = 76.67 mph north.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />
<br />
==Connectedness==<br />
<br />
Velocity is a very interesting and important topic. Take into consideration pilots. flying an aircraft Pilots must combat strong winds while they are thousands of feet up in the air. It is not very useful for a pilot to know that the wind is traveling at 80 mph. What direction is it traveling in? The direction of this wind could prove to be useful, or to be a nightmare for the pilot! Pilots must know whether they are flying with the wind, or against the wind. <br />
<br />
Also, take into consideration sports. In baseball, when the pitcher throws the ball to the batter, the batter must make a decision as to what he/she wants the ball's velocity to be. The ball can either go fast or slow (magnitude), or left or right (direction), etc. This immediate decision plays a huge role in how each team will increase their score during the game.<br />

where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

Velocity is a very interesting and important topic. Take into consideration pilots. flying an aircraft Pilots must combat strong winds while they are thousands of feet up in the air. It is not very useful for a pilot to know that the wind is traveling at 80 mph. What direction is it traveling in? The direction of this wind could prove to be useful, or to be a nightmare for the pilot! Pilots must know whether they are flying with the wind, or against the wind. <br />
Also, take into consideration sports. <br />

<br />
Velocity is the time rate of change of position of a body in a specified direction. It is a vector quantity that consists of a magnitude and direction. Speed is also the change of position of a body; however, it does not take the object's direction into consideration.<br />
<br />
==Equation==<br />
<br />
Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Example==<br />
<br />
[[File:Caronroad.jpg|thumb|alt=Example|3 hour, 230-mile trip]]<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />

|-<br />
|}<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
Given the example: Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Given the example: The average velocity would be (230 miles/3 hours) = 76.67 mph north.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />

[[File:Whatisvelocity.gif|thumb|alt=Definition|What is velocity?]]<br />
<br />
Velocity is the time rate of change of position of a body in a specified direction. It is a vector quantity that consists of a magnitude and direction. Speed is also the change of position of a body; however, it does not take the object's direction into consideration.<br />
<br />
==Equation==<br />
<br />
Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
<br />
===A Computational Model===<br />
<br />
Velocity is a quantity that reappears several times when considering the Momentum Principle. The Momentum Principles states that,<br />
<math>{\Delta\boldsymbol{p}}</math> = Force<math>{\Delta\boldsymbol{t}}</math><br />
<br />
==Example==<br />
<br />
[[File:Caronroad.jpg|thumb|alt=Example|3 hour, 230-mile trip]]<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />
<br />
{| border="1"<br />

|-<br />
! Velocity<br />
| 80 mph north || 90 mph north || 60 mph north<br />
|-<br />
|}<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
Given the example: Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Given the example: The average velocity would be (230 miles/3 hours) = 76.67 mph north.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

<br />
Velocity is the time rate of change of position of a body in a specified direction. It is a vector quantity that consists of a magnitude and direction. Speed is also the change of position of a body; however, it does not take the object's direction into consideration.<br />
<br />
==Equation==<br />
<br />
Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Example==<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />
<br />

|-<br />
! Velocity<br />

|-<br />
|}<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
Given the example: Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Given the example: The average velocity would be (230 miles/3 hours) = 76.67 mph north.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Example==<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />

<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
Given the example: Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Given the example: The average velocity would be (230 miles/3 hours) = 76.67 mph north.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Given the example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
For example: For the first hour, the car travels at 80 mph east. For the second hour, the car travels at 90 mph north. For the third and final hour, the car travels at 60 mph north. Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Looking at the previous example: The average velocity would be (230 miles/3 hours) = 76.67 mph.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />

The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Continuing with the previous example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Examples==<br />
<br />
A car takes 3 hours to make a 230-mile trip from Point A to Point B. <br />

|-<br />
|}<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
For example: For the first hour, the car travels at 80 mph east. For the second hour, the car travels at 90 mph north. For the third and final hour, the car travels at 60 mph north. Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Looking at the previous example: The average velocity would be (230 miles/3 hours) = 76.67 mph.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Continuing with the previous example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />

|name = Velocity<br />
<br />
Velocity is the time rate of change of position of a body in a specified direction. It is a vector quantity that consists of a magnitude and direction. Speed is also the change of position of a body; however, it does not take the object's direction into consideration.<br />
<br />
==Equation==<br />
<br />
Average velocity can be calculated using the following equation:<br />
:<math>\boldsymbol{\bar{v}} = \frac{\Delta\boldsymbol{r}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{r}}</math> is the change of position of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for velocity are ''meters per second (m/s)''. <br />
<br />
==Examples==<br />
<br />
There are two kinds of velocity in which one must consider: instantaneous velocity and average velocity.<br />
<br />
===Instantaneous Velocity===<br />
<br />
Instantaneous velocity is the speed and direction of an object at a particular instant.<br />
<br />
For example: A car takes 3 hours to make a 230-mile trip from Point A to Point B. For the first hour, the car travels at 80 mph east. For the second hour, the car travels at 90 mph north. For the third and final hour, the car travels at 60 mph north. Each hour has a different instantaneous velocity.<br />
<br />
===Average Velocity===<br />
<br />
Average velocity is the net displacement of an object, divided by the total travel time. It is the average of all instantaneous velocities.<br />
<br />
Looking at the previous example: The average velocity would be (230 miles/3 hours) = 76.67 mph.<br />
<br />
==Acceleration==<br />
<br />
Acceleration is the time rate of change of velocity, with the following equation:<br />
:<math>\boldsymbol{a} = \frac{\Delta\boldsymbol{v}}{\Delta\mathit{t}}</math> , <br />
where <math>{\Delta\boldsymbol{v}}</math> is the change of velocity of the object and <math>{\Delta\mathit{t}}</math> is the change of time.<br />
<br />
The SI units for acceleration are ''meters per second per second (m/s/s)''. It is also a vector quantity.<br />
<br />
Continuing with the previous example: The acceleration from the 1st hour to the 2nd hour is 10 mph. This indicates a positive acceleration. The acceleration from the 2nd hour to the 3rd hour is -30 mph. This indicates a negative acceleration.<br />
