Question

what is rest and motion?​

Answer 1

According to the theory of relativity, it is said that an object is "at rest relative to" another. Two or more than two objects are said to be at rest, if its position with respect to each other is not changing or moving with uniform velocity with respect to each other; rest and motion are relative terms.
