Velocity

Velocity is defined as how quickly a body changes position in a direction. It is a vector.

Notice that a higher velocity yields a greater change in position. (40 miles versus 20 miles) Velocity is used to calculate the change in postion.

Example

In a race an athlete is traveling at a constant velocity of 10 m/s. After 6 seconds how far will the runner have traveled?

Givens
v = 10 m/s
