The rocket's engine expels out hot gases(produced due to the burning of fuel)with large speed downward direction from its rear end. An equal and opposite reaction acting on the rocket pushes the rocket in the upward direction

How Rocket Works According to the Principle of Conservation of Momentum

Rocket propulsion is based on the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant if no external forces act on it. In the case of a rocket, the ejection of mass at high velocity generates a reactive force that propels the rocket forward.

Principle of Conservation of Momentum
- The principle of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces act on it.
- In a rocket, the ejection of mass at high velocity generates a reactive force that propels the rocket forward.

Newton's Third Law of Motion
- Newton's third law states that for every action, there is an equal and opposite reaction.
- When the rocket expels mass at high velocity, it generates a reactive force that propels the rocket forward.

Propulsion Mechanism
- The rocket engine burns fuel to produce hot gases at high pressure.
- These gases are expelled at high velocity through a nozzle, creating a reactive force that propels the rocket forward.

Conservation of Momentum in Action
- As the rocket expels mass at high velocity, it gains momentum in the opposite direction.
- This increase in momentum propels the rocket forward, following the principle of conservation of momentum.

By harnessing the principle of conservation of momentum, rockets are able to propel themselves through the vacuum of space and reach incredible speeds. This fundamental principle of physics underlies the mechanics of rocket propulsion and enables humans to explore the vast expanse of outer space.
