An object is deemed to be moving, or in motion, when there is a change in position of an object compared to a stationary object. An object is deemed to be moving, or in motion, when there is a change in position of an object compared to a stationary object. Minor edit?
An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in a closed system does not change with time, as described by the law of conservation of momentum. As there is no absolute frame of reference, absolute motion cannot be determined.
