How are the states of rest and motion relative?

Explanation:

Rest and motion are the relative terms because they depends 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.

Final Answer:

Hence, the states of rest and motion are relative because they depend upon the observer’s frame of reference.
