The Rocket engine works on the basic principle proposed by Newton which is- Newton’s Third Law “For every action there is an equal and opposite reaction.”
In rocket engine, the fual and the oxidizer are passed though pipes with the help of high speed pumps.
Under the high pressure both are mixed in the combustion chamber, where they ignite.
A large amount of hot gases are released under high pressure through the nozzle.
This results in an upwards thrust against gravity, which propels it into space.
