- The thrust of rocket engines is generated by123:
- Accelerating a mass of gases at high velocity out of an expansion nozzle.
- The reaction force associated with this gas acceleration.
- The design of the nozzle, mass flow rate, exit velocity of the exhaust, and pressure at the nozzle exit.
- Thrust is measured in pounds or Newtons.

To view the original source information, use the "Learn more" links.Thrust is produced according to Newton’s third law of motion. Thrust The amount of thrust produced by the rocket depends on the mass flow rate through the engine, the exit velocity of the exhaust, and the pressure at the nozzle exit. All of these variables depend on the design of the nozzle.www1.grc.nasa.gov/beginners-guide-to-aeronautic…The "strength" of a rocket engine is called its thrust. Thrust is measured in "pounds of thrust" in the U.S. and in Newtons under the metric system (4.45 Newtons of thrust equals 1 pound of thrust). A pound of thrust is the amount of thrust it would take to keep a 1-pound object stationary against the force of gravity on Earth.science.howstuffworks.com/rocket.htmThe principle of thrust generation for a rocket engine is from the reaction force associated with accelerating a mass of gases at high velocity out of an expansion nozzle, the gases being a byproduct of combustion of the fuel and the oxidizer, and so increasing the kinetic energy and momentum of the gases.eaglepubs.erau.edu/introductiontoaerospaceflightv… Comparison of orbital rocket engines - Wikipedia

Rocket engine - Wikipedia
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. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as
