Motion may refer to: Motion (physics), any movement or change in position or time. Motion in United States law, a procedural device in law to bring a limited, contested matter before a court. Motion (democracy), a formal step to introduce a matter for consideration by a group.
Motion is change of location or position of an object with respect to time. Change in motion is the result of an applied force. Motion is typically described in terms of velocity also seen as speed, acceleration, displacement, and time. However, the motion of an object is only relative to the position of another object.
