If the displacement of a body is zero



If the displacement of a body is zero, is it necessarily zero? Answer with one example.


No, because the distance covered by an object is the path length of the path covered by the object. The displacement of an object is given by the change in position between the initial position and final position.
e.g. A boy starts from his home and moves towards market along a straight path. Then, he returns to home from the same path. Here, displacement is zero but distance is non-zero.
