Rocket fuel is a substance that is used to propel rockets. It is typically a liquid or a solid, and it contains a fuel and an oxidizer. When the fuel and oxidizer are combined, they undergo a chemical reaction that produces hot gases. These gases are then expelled out of the rocket nozzle, which creates thrust and propels the rocket forward.
Rocket fuel is an essential part of rocketry. Without it, rockets would not be able to fly. Rocket fuel has been used for centuries to power rockets, and it has played a major role in the development of space exploration. Today, rocket fuel is used in a variety of applications, including satellites, launch vehicles, and spacecraft.
