Question

when the displacement covered by a moving object is zero​

Answer 1

Answer:

The displacement of a moving object in a given interval is zero i.e., the object comes back to its initial position in the given time (displacement is the shortest distance between the initial and final position of an object).

Answer 2

Answer:

When the body starts from a initial position and at last reaches again to the initial position, its displacement becomes zero. e.g. Think of a car traveling in a circular path.

When the car reaches from where it started its displacement becomes zero.
