A wrench, a jack, and a crowbar, used for changing tires are all "simple machines".
2. Any device that transmits, modifies, or magnifies forces for a specific purpose.Machines typically either alter the amount of force applied, or the direction along which it is applied. A simple machine is a machine with only one or two parts.
matter
1. A physical substance that occupies space, possesses mass, and is ultimately convertible to energy.
Matter can be a gas, liquid, or solid.
2. The substance of the universe; made up of atomic particles, atoms, and molecules.Matter exists in four familiar states: solid, liquid, gas, and plasma (gas consisting of electrons and ions).
mechanics
A branch of physics concerned with the study of bodies in motion.
