How do rockets work?

Rockets work based on the principles of propulsion, combustion, and acceleration. They function on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

Propulsion

The propulsion of a rocket is created by the burning of fuel in the rocket engine. The fuel, typically a combination of liquid hydrogen and liquid oxygen, is ignited in the combustion chamber, producing hot gases that are expelled through the rocket nozzle at high speeds. This expulsion of gas in one direction causes the rocket to move in the opposite direction.

Combustion

Combustion occurs when the fuel is mixed and ignited, releasing energy in the form of heat. This heat leads to the expansion of gases, creating a high-pressure environment within the combustion chamber. The pressure forces the gases out of the rocket nozzle, propelling the rocket forward.

Acceleration

As the rocket expels hot gases at high speeds, it experiences an equal and opposite reaction, causing it to accelerate in the opposite direction. This acceleration allows the rocket to overcome Earth's gravity and lift off into space.

In conclusion, rockets work by harnessing the principles of propulsion, combustion, and acceleration to generate the thrust needed to launch into space and explore beyond our atmosphere.
