Question

Displacement may be zero.Even distance travelled is not zero? Is it true? Is the reverse of this is true ? Give examples?

Answer 1

yes it is true if the displacement can be zero even distance is not zero if the body is coming back to its initial position. like in circular motion if you start from a point A and returning back to the point then distance is equal to 2πr but displacement will be zero.

No it is not possible the distance is zero because it is a scalar quantity.
