Motion (physics) In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. Motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
What does displacement mean? If an object moves relative to a reference frameâfor example, if a professor moves to the right relative to a whiteboard, or a passenger moves toward the rear of an airplaneâthen the objectâs position changes. This change in position is known as displacement.
