Question

Say how motion is relative to the observer, SCERT telangana class 7 with examples

Answer 1

A body may be at rest with respect to one  set of surroundings and at the same time be  in motion with respect to another set of  surroundings

Examples :

• The man in the boat is moving with respect to  the bank of river. He is at rest with respect to  the boat

Thus motion is relative to the observer

Answer 2

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.
