In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement,velocity, acceleration, and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant position.
