Answer 2

● Rest - a body is said to be at rest, if it does not change its position with respect to its surrounding with time.

● Motion - a body is said to be at motion, if it changes its position with time.

● 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.
