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.) Power of, or capacity for, motion.
(n.) Direction of movement; course; tendency; as, the motion of the planets is from west to east.
(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.
(n.) Change of pitch in successive sounds, whether in the same part or in groups of parts.
(n.) A puppet show or puppet.
(v. i.) To make a significant movement or gesture, as with the hand; as, to motion to one to take a seat.
