Can a body be at rest as well as in motion at the same time? Explain.         Or Rest and motion are relative terms. Explain.

Answer:

                Yes, object may be at rest relative to one object and at the same time it may be in motion relative to another object. For example, a passenger sitting in a moving train is at rest with respect to his fellow passengers but he is in motion with respect to the objects outside the train. Rest and motion are relative terms.
