Question

While at soccer practice, Abbey runs down the field at 10 meters per second. She has a constant speed and does not change direction. What is Abbey's acceleration?
A.

The acceleration is 0 m/s^2 because her velocity did not change.

B.

The acceleration is 10 m/s^2 because her velocity increased.

C.

The acceleration is 0 m/s^2 because her velocity increased.

D
.

The acceleration is 10 m/s^2 because her velocity did not change.

Answer 1

A.

Acceleration is the rate of change of velocity. Since Abbey's speed and direction stay constant, her velocity doesn't change, so her acceleration is 0 m/s^2.
