प्रश्न
Give an example of a body which covers a certain distance, but its displacement is zero.

उत्तर
Yes, displacement of a body can be zero even if the distance covered by it is not zero. For example, if a body moves in a circle, then displacement of the body in one rotation is zero but the distance covered by it in one rotation = 2πr, where r is the radius of the circle in which the body is moving.
