physics

Physics is a kind of science, specifically the science of matter and energy and how they interact.

Physics is the study of physical matter, energy, and how they work together. Kinetic energy and potential energy are part of physics. Although it may sound really advanced — and it is — physics is involved in everything we do. Champion pool players have a good understanding of how physics influences the movement of the balls. People who design roller coasters better know their physics. And if you've ever rigged up a pulley or a lever, then you've done basic physics.
