means A change in position, posture, or state — the act of moving, whether of a body, a crowd, a cause, or a clock's inner gears.

from From Old French 'movement,' built on Latin 'movere,' to move — the same root that powers 'motion,' 'motor,' 'emotion,' and even 'mob' (literally 'the movable crowd'). The political sense (a 'movement' of people toward a goal) and the musical one (a 'movement' within a symphony) both bloomed later, each borrowing the idea that something is going somewhere.
