explain the working of rocket
Answers
Answer:
A space rocket is a vehicle with a very powerful jet engine designed to carry people or equipment Earth and out into space. If we define space as the region outside Earth's atmosphere, that means there's not enough oxygen to fuel the kind of conventional engine you'd find on a jet plane. So one way to look at a rocket is as a very special kind of jet-powered vehicle that carries its own oxygen supply. What else can we figure out about rockets straight away? They need great speed and a huge amount of energy to escape the pull of gravity and stop them tumbling back down to Earth like stones. Vast speed and energy mean rocket engines have to generate enormous forces. How enormous? In his famous 1962 speech championing efforts to go to the Moon, US President John F. Kennedy compared the power of a rocket to "10,000 automobiles with their accelerators on the floor." According to NASA's calculations, the Saturn V moon rocket "generated 34.5 million newtons (7.6 million pounds) of thrust at launch, creating more power than 85 Hoover Dams."

Explanation:
the momentum of rocket before it is fired is zero when the rocket is fired gases are produced the amount of a real of rocket with high speed the direction of the moment term of the gases coming out of the rope it is in downward direction does to conserve the momentum of this complete system that is rocket the stresses the rocket moves upward with the momentum equal to the momentum of the dress so the rocket continues to move upward as long as yes is injected out of the rocket does a rocket works on the basis of law of conservation of momentum
