The term Movement has a variety of different meanings:
Physical movement between points in space ("A to B"). The amount of movement is called distance. Together with a direction you have a displacement. The rate of movement is the speed. Again, with the direction, you get the velocity. Active movement is called locomotion. See also under motion and transport.
Biologically a movement or bowel movement refers to the elimination of solid waste from the body.
In Aviation, the amount of traffic that an airport handles is described in movements per year, where one "movement" consists of a aircraft taking off or landing.
