Question

how can you say that rest and motion are relative terms.

Answer 1

Rest and motion are relative terms. Explain. Answer: 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.

Answer 2

Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two differentobservers are not at rest with respect to each other, then they too getdifferent results when they observe themotion or rest of a body.
