Here's a breakdown:
* Combustion: A rocket engine burns fuel, creating hot, high-pressure gas.
* Expansion: This gas is then rapidly expanded through a nozzle, like a funnel, which directs the flow.
* Newton's Third Law: As the hot gas is expelled out of the nozzle at high speed, an equal and opposite force is exerted on the rocket, pushing it in the opposite direction – forward.
In simpler terms: The rocket engine pushes the hot gas backward, and the gas pushes the rocket forward. This is the principle of action and reaction as described by Newton's Third Law of Motion.
