Motion
Definition:
(n.) The act, process, or state of changing place or position; movement; the passing of a body from one place or position to another, whether voluntary or involuntary; -- opposed to rest.

(n.) Change in the relative position of the parts of anything; action of a machine with respect to the relative movement of its parts.
(n.) Movement of the mind, desires, or passions; mental act, or impulse to any action; internal activity.
(n.) A proposal or suggestion looking to action or progress; esp., a formal proposal made in a deliberative assembly; as, a motion to adjourn.
(n.) An application made to a court or judge orally in open court. Its object is to obtain an order or rule directing some act to be done in favor of the applicant.
