The fundamental principle behind rocket propulsion is Newton's Third Law of Motion : for every action, there is an equal and opposite reaction.

Modern orbital rockets are complex systems typically composed of four main parts: Rocket

: Inside the combustion chamber, propellant (fuel and oxidizer) burns at high pressure and temperature. Rocket

: This high-pressure gas is expelled through a specially shaped De Laval nozzle . The nozzle accelerates the gas to hypersonic speeds—sometimes ten times the speed of sound—converting thermal energy into kinetic energy. Rocket

: As the gas is forcefully ejected downward, it creates an upward force called thrust that propels the rocket. Anatomical Structure of a Rocket
