Motion.
Synonyms:
| act, | change, | movement, | process, | transition. |
| action, | move, | passage, | transit, | |
Motion is change of place or position in space; transition is a passing from one point or position in space to another. Motion may be either abstract or concrete, more frequently the former; movement is always concrete, that is, considered in connection with the thing that moves or is moved; thus, we speak of the movements of the planets, but of the laws of planetary motion; of military movements, but of perpetual motion. Move is used chiefly of contests or competition, as in chess or politics; as, it is your move; a shrewd move of the opposition. Action is a more comprehensive word than motion. We now rarely speak of mental or spiritual motions, but rather of mental or spiritual acts or processes, or of the laws of mental action, but a formal proposal of action in a deliberative assembly is termed a motion. Compare ACT.
