The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero ? Justify you answer.

Option A

Option B

Option C

Option D

Solution

When the displacement is zero, it does not mean that distance is also zero. Displacement can be zero when the moving object comes back to its original position. Displacement is either equal to or less than distance but distance travelled is always more than zero.
