Question

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

Answer 1

★ A body is said to be in motion if its position with respect to the observer changes.

★ The houses on the street are in motion relative to us.

Answer 2

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

• 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
