How Does a Rocket Work?

Like most engines, rockets burn fuel. Most rocket engines convert fuel into hot gas coming out of their backs. So they have to use liquid fuel. The fuel (liquid hydrogen, gasoline, or kerosene for example) is pumped into a combustion chamber with an oxidizer (like liquid oxygen) and then burned into a very high-pressure gas. The gas is forced out the back of the rocket, forcing the rest of the shuttle forward.

In 1926, Robert Goddart tested the first liquid rocket engine. The engine uses gasoline and liquid oxygen.

The idea was initially simple. In most liquid fuel rockets, fuel and oxidizers (eg, gasoline and oxygen) are pumped into the combustion chamber. There they are burned to create a gas vapor with high pressure and speed. The gas flows through a nozzle that accelerates it further (5000 to 10,000 mph), and exits the engine.

In outer space, rocket engines can not push back / push thrust. So how does a rocket move outside of space? The rocket works with a scientific rule called Newton's third law of motion. British scientist Sir Isaac Newton listed three Laws of Motion. He did this over 300 years ago. The third law says that for every action, there is an equal and opposite reaction. Law of reaction action. The great power (action) generated by hot gas firing back from the rocket engine produces the same force (reaction) that propels the rocket forward through space.
