Question

Is displacement can be 0 ? if so give reason.

Answer 1

Displacement can be zero.. if a body has not covered any length due to its motion.
A body can have 0 displacement if it is stationary or.. is at rest.
Hence there is no difference in the initial position of the body and its final position

Answer 2

yes displacement can be zero if a body starts from a fixed initial point and ends up its motion at the same point...which means the initial and final position of the body is Same ,..then the displacement is zero...

e.g. A man is running on a circular track from a initial point and ends his run at the same point....
