Rocket works on the principle of conservation of momentum. Rocket ejaculates gases in backward direction which creates momentum of the gases backwards and thus by conservation of momentum, the rocket gets a momentum in the forward direction making it to move forward.

Principle of Rocket Working
Rockets operate based on fundamental principles of physics, primarily the conservation of linear momentum and Newton's third law of motion.
Newton's Third Law of Motion
- For every action, there is an equal and opposite reaction.
- When a rocket expels gas at high speed in one direction, it experiences a thrust in the opposite direction.
- This reaction force propels the rocket upward or forward.
Conservation of Linear Momentum
- Momentum is conserved in a closed system where no external forces are acting.
- As the rocket expels exhaust gases, it loses mass but gains speed in the opposite direction.
- The total momentum before and after the gas is expelled remains constant.
How It Works in Practice
- The rocket engine burns fuel, creating high-pressure gas.
- This gas is ejected out of the nozzle, generating thrust.
- The change in momentum of the expelled gases results in a change in the rocket's momentum, propelling it forward.
Application of These Principles
- The design of rocket engines is optimized to maximize the speed and efficiency of expelled gases.
- The thrust produced must overcome the gravitational force and drag to achieve lift-off.
In summary, the working principle of rockets is a perfect demonstration of the conservation of linear momentum and Newton's third law of motion, enabling them to travel through space effectively.
