Question

Explain giving an example that an object can be in motion as well as at rest at the same time.

Answer 1

Rest and Motion are Relative Terms.

An object which is at rest can also be in motion with respect to different refernce points.

eg.) A passenger travelling in a bus; the passenger is at rest with respect to the fellow passengers but it is in motion with respect to the ground

A rock is rest with respect to person in earth

And in motion with respect to a man in other planet as earth rotate sun
