Jet engines operate based on the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In the case of jet engines, air is drawn into the engine, compressed, mixed with fuel, ignited, and then expelled at high speed through a nozzle, generating thrust. This process is known as the Brayton cycle, which is the thermodynamic cycle that describes the functioning of the jet engine.
