propellant

adj. pushing, thrusting, driving; moving forward, propelling forward

n. explosive material used to drive ammunition rockets and other projectiles

A propellant is a material that is used to move an object by applying a motive force. This may or may not involve a chemical reaction. It may be a gas, liquid, plasma, or, before the chemical reaction, a solid. Common chemical propellants consist of a fuel, like gasoline, jet fuel and rocket fuel, and an oxidizer.
