On which laws is the principle of rocket propulsion based?

The propulsion of all rockets is explained by the same physical principle of Newton’s third law of motion.  It states that every motion has an equal and opposite reaction. The propulsion of a rocket includes all the parts which make up the rocket engine; the tanks pumps, propellants, powerhead, and rocket nozzle.

Rockets are based on Newton’s third law

The function of the propulsion system is to produce thrust. Thrust is the force that moves a rocket through the air and through space. The engine of the rocket releases hot burning fuel in a downward direction and the gases apply equal and opposite force and push the rocket in the upward direction.
