I push a ball on the ground and it comes to rest after some time. It is a case of motion turning into rest. I think every person, whether he be on Earth, Moon, or in any other part of the universe will see the ball coming to rest. If you attach a reference frame to the ball itself, the person in this frame will also see/feel that he is decelerating and coming to rest. So, the whole universe will agree that ball is at rest. So where is relativity? I am talking only about the motion of ball.
