Question

Give two examples which show that state of rest and state of motion are relative terms.​

Answer 1

Yes motion is a relative term, it totally depends upon the observer. Since observer can be still or be moving that's why it is relative term.

Like if you are sitting on a train and it is standing at the platform then person standing on the platform will look like at rest.

But if train start Moving forward and the person standing at the platform is still at rest the person on the train will feel person on the platform is moving backward.

And if you see at the perspective of platform person the man sitting in the train is moving forward. But if you look both of them they think itself at rest and others at motion.
