How is motion related to rest

Answer 1

you can understand this easily by an example.

when you're sitting in a moving bus , the bus is in motion and according the people in the bus you're in rest and according to the people outside the bus you're in motion. but you're sitting in a moving bus which has motion.
according to newtons law, you're too in motion because your body is in contact with the bus.


this is the relation between motion and rest.
