A chemical rocket is a type of propulsion system that uses chemical reactions to produce thrust. It typically consists of a fuel and an oxidizer, which, when combined and ignited, create high-pressure gases that are expelled through a nozzle. This process follows Newton's third law of motion, where the action of the gases being pushed out results in the rocket moving in the opposite direction. These rockets are commonly used in space exploration and satellite launches. Notable examples include the Saturn V, which took astronauts to the Moon, and the Space Shuttle, which transported cargo and crew to low Earth orbit.
