Question

Which statement is the best description of acceleration?
O Acceleration is any change in speed.
O Acceleration is any change in displacement.
O Acceleration is any change in total distance.
O Acceleration is any change in velocity.

Answer 1

Answer:

Acceleration is any change in velocity.

Explanation:

Speed is not always changing when accelerating. In fact, when an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. So the correct answer is velocity.
