Synonym Usage
Motion, move, movement refer to change of position in space. Motion denotes change of position, either considered apart from, or as a characteristic of, something that moves; usually the former, in which case it is often a somewhat technical or scientific term: perpetual motion. The chief uses of move are founded upon the idea of moving a piece, in chess or a similar game, for winning the game, and hence the word denotes any change of position, condition, or circumstances for the accomplishment of some end: a shrewd move to win votes. Movement is always connected with the person or thing moving, and is usually a definite or particular motion: the movements of a dance.

Etymology
Origin of motion
First recorded before 1350–1400; Middle English mocio(u)n, from Latin mōtiōn- (stem of mōtiō ), equivalent to mōt(us) (past participle of movēre move ) + -iōn- -ion
Explanation
Motion is the way things get from place to place. The ball rolling down a hill is in motion, and as Isaac Newton once proved, it will remain in motion until it hits a wall or something else that makes it stop. When motion is used as a noun, it describes movement, like the motion that propels a car from one end of the highway to another. When used as a verb, motion means to signal or direct. "A restaurant patron will motion to the server when he's ready for the check." Someone who is just "going through the motions" doesn't have to move at all, because they're just pretending.
