Science glossary film: Motion

Or movement. In physics, motion is a change in position in space over time. Motion is described in terms of velocity, acceleration, displacement, and time. Newton's Laws of motion, formulated over 300 years ago, still provide the basic mathematical tools to describe motion in most systems.
