Question

Principle of rocket working

Answer 1

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.

Answer 2

A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. The air inside a balloon is compressed by the balloon's rubber walls. The air pushes back so that the forces on each side are balanced. When the nozzle is released, air escapes through it and the balloon is propelled in the opposite direction.
