Rocket propulsion refers to the process of generating thrust through the expulsion of exhaust gases at high velocities to propel rockets forward. It is usually achieved by the combustion of chemical propellants that generate the forces pushing the rocket against gravity into motion. The principle behind this is Newton's Third Law of Motion, which states that for any action, there is an equal and opposite reaction.
