Question

Can a body exist in a state of absolute rest or of absolute motion?explain.

Answer 1

Rest and motion are always relative. A body cannot exist at a state of absolute rest or absolute motion. For example, two persons sitting in a moving bus are at rest w.r.t each other but are in motion w.r.t. a person standing on the roadside. Further, trees, buildings, etc on the surface of the Earth appear to be at rest but infact they are in motion as the Earth revolves around the Sun. Thus, there is no object which can be condisered to be at absolute rest. Hence, rest and motion are relative terms.
