A fast-moving body must have a larger acceleration than a slow-moving body.

Question

Quizplus · Accepted Answer

This statement is false. Acceleration is the rate of change of velocity, and velocity is the rate of change of displacement. Therefore, a body can have a large acceleration with a small change in velocity if it covers a small distance in a short time, even if it is slow-moving. Similarly, a body can have a small acceleration with a large change in velocity if it covers a large distance in a long time, even if it is fast-moving.
