• mechanical energy

• kinetic energy

• subliminal energy

All matter consists of tiny particles that are in constant motion.

• Law of conservation of energy

• kinetic theory

• potential theory

• Newton's 1st law

results from the force exerted by a gas per unit surface area of an object

• liquid pressure

• solid pressure

an empty space with no particles and no pressure
