Question

Motion and rest are relative but never absolute.Why? Justify with example.

Answer 1

Rest and motion are the relative terms because they depend on the observer’s frame of reference. If an observer is at rest in his or her own frame of reference, but he may be moving in other observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.
