Referring to any of Newton's three main laws of physics.

-An object in motion/not in motion will stay that way unless acted on by an outside force (also known as inertia).

-The force of an object is equal its mass times its acceleration (also known as F=MA)

- When one mass exerts a force on another mass, the other mass exerts a force equal in magnitude but opposite in direction (also known as the Action/Reaction law)
