1. Why rest and motion are called relative terms?​

Answer 1

Rest and motion are related terms. Without any reference object to relate with it isn't possible to mention whether a object is in rest or motion.

It is best understood through examples-

For example- Let it be that you are travelling in a bus. 

So to you all other passengers are in rest.

However for a person who's outside the bus, everyone inside the bus is moving.

Hence, in the first example when you are the reference object, the passangers are stationary that is in rest.

But on the other hand, when the reference object is a person outside the moving bus, the same passengers are in motion that is moving.

Answer 2

Answer:

HEY MATE.

GOOD AFTERNOON..

REST AND MOTION ARE RELATIVE TERMS BECAUSE THEY DEPEND UPON THE OBSERVER'S FRAME OF REFERENCE.

SO IF TWO DIFFERENT OBSERVER ARE NOT AT REST WITH RESPECT TO EACH OTHER,then they two get different result.when they observe motion or rest of a body.
