A rocket is a vehicle designed to travel into space. It works by burning fuel to create a powerful force that pushes it upward. This force is called thrust, and it allows rockets to break free from Earth's gravity. Rockets are used for various purposes, including launching satellites, exploring other planets, and sending astronauts into space. Rockets come in different shapes and sizes, but they all share a similar design. The main parts of a rocket include the propellant, which provides the fuel, and the payload, which is the cargo or passengers being sent into space. Famous rockets like the Saturn V and the SpaceX Falcon 9 have made significant contributions to space exploration.
