Consider a car driving around a circular track. Once started, the driver maintains a speed of 45 m/h. Compare the driver's velocity with his acceleration in this case.
AThe car is accelerating because it is changing direction but the velocity is constant.
BThe car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change.
CAcceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
DThe car is traveling at a constant rate of speed so it is not accelerating but the velocity changes because the direction the car travels is constantly changing.
