Rockets work by burning a fuel source. There are liquid engines and solid engines.
Solid rocket engines work just like fireworks. The engine is ignited and the solid fuel inside them burn until they burn out. The thrust caused from the burning fuel is directed out the nozzle of the rocket. That pushed the rocket in the opposite direction.
Liquid fuel engine work in the same way, but they use liquid fuel just like a car does.
One way to think of it is to think of a balloon. A balloon expands because the air pressure inside is pressing against all of the interior of the balloon at the same pressure. When you let go of the end of the balloon, the air is pushing out of the end of the balloon and that action caused the balloon to move in the opposite direction.
For every action there is an equal but opposite reaction.
During a rocket launch, the thrust of the rocket engine is greater than the weight of the rocket. This is necessary for the rocket to overcome Earth's gravitational pull and lift off into space. The thrust generated pushes the rocket upwards while gravity pulls it down.
A spaceship is a vehicle designed for travel in outer space, often equipped to carry humans or cargo, while a rocket is a propulsion system that provides the thrust needed to launch a spacecraft into space. Rockets can be used independently or as part of a spacecraft, serving as the means of escape from Earth's gravity. Essentially, the rocket is the engine, and the spaceship is the vehicle that often incorporates the rocket for space travel.
The average thrust of a rocket motor varies widely depending on the type and size of the rocket. Small solid rocket motors can produce thrust in the range of a few thousand pounds, while large liquid rocket engines, like those used in space launch vehicles, can generate millions of pounds of thrust. For example, NASA's Space Launch System (SLS) generates about 8.8 million pounds of thrust during liftoff. Thus, average thrust can range from thousands to millions of pounds, depending on the application.
Thrust, gravity and upthrust help launch a rocket.
Bob asks you to find the three rocket parts - the Launch Button, the Thrust Unit, and the Control Module - in order to repair the spaceship and escape from the Maelstrom's forces in LEGO Universe.
The part at the bottom of a rocket is called the "rocket engine" or "thrust nozzle." This is where the propulsion system is located, generating the thrust needed to lift the rocket into space. It often includes components like fuel tanks and pumps, which work together to produce the necessary force for launch.

Weight refers to the force of gravity acting on the rocket, thrust is the force propelling the rocket upward, lift is the force generated by the rocket's fins to keep it stable, and drag is the resistance encountered as the rocket moves through the air. Weight must be overcome by thrust for the rocket to launch, while lift helps the rocket maintain stability and drag opposes its forward motion. Balancing these forces is crucial for a successful rocket launch.
A rocket is said to launch when it leaves the ground -- is thrust into the sky.
The amount of thrust needed to launch a rocket varies depending on the size, weight, and destination of the rocket. On average, rockets require anywhere from hundreds of thousands to millions of pounds of thrust to overcome Earth's gravity and achieve orbital velocity. For example, the Saturn V rocket used during the Apollo missions had a maximum thrust of 7.6 million pounds.
Booster stage
The rocket engines ignited, providing the necessary thrust to lift the spacecraft off the launch pad.
