- Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that "to every action there is an equal and opposite reaction." A rocket engine is throwing mass in one direction and benefiting from the reaction that occurs in the other direction as a result.

A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law.
Sep 21, 2010 · When most people think of a rocket, they think of a tall round vehicle that flies into space. The word can describe a type of engine or to talk about a vehicle that uses a rocket engine.
Nov 20, 2023 · Rocket Engine. In a rocket engine, fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust. For a rocket, the accelerated gas, or working fluid, is the hot exhaust produced during combustion ...
In the case of rockets, the action is the force produced by the expulsion of gas, smoke, and flames from the nozzle end of a rocket engine. The reaction force propels the rocket in the opposite direction.When a rocket lifts off, the combustion products from the burning propellants accelerate rapidly out of the engine.
Jul 13, 2011 · “Rocket” can mean a type of engine. The word also can mean a vehicle that uses that engine. NASA’s Saturn V rocket carried humans to the moon. Credits: NASA. How Does a Rocket Engine Work? Like most engines, rockets burn fuel. Most rocket engines turn the fuel into hot gas. The engine pushes the gas out its back.
