Question

A moving particle has average speed equal to magnitude of average velocity over a certain interval. Which statements can be true?

G1 Physics · Accepted Answer

Equality requires distance = |displacement|, so no reversal occurs. The magnitude of velocity may still change, and the particle may momentarily stop without reversing. Hence A, B and C can be true. D is not necessary.
