Hi Friend,
Your question is a brainy one ,i will try to answer it,, hope it helps you.
A substance is referred to be in state of motion when it changes its position from one place to another with respect to a fixed object in its surrounding.
A stationary object like a piece of paper is said to be in motion only when we can
see that it has changed its position or not or if there is a can lying near the same paper and it flies due to wind and comes near a tree far from the can then the paper was in motion.
