Question

Give an example of a motion in which the displacement is zero, but the distance travelled is not zero.

Answer 1

Displacement can be zero even when distance is not zero.

Consider two points A and B such that AB = 5 m.

When a car travels from A to B and then back from B to A, distance = 5+5 = 10 m.

Displacement = Minimum distance between final(B) and initial position(B) = 0.
