Rocket Propulsion
Rocket propulsion is the method of moving a spacecraft by expelling gas at high speed. It works on Newton's Third Law: for every action, there's an equal and opposite reaction. When a rocket burns fuel, it releases hot gases out of its engines. The force generated by these gases pushes the rocket in the opposite direction, propelling it forward. This technique allows rockets to overcome Earth's gravity and travel into space. Rocket propulsion systems can be powered by solid or liquid propellants, each with distinct advantages for different missions.

Rocket propulsion operates on Newton's Third Law of Motion: for every action, there's an equal and opposite reaction. Rockets generate thrust by expelling gas at high speed from their engines. The fuel and oxidizer are ignited in a combustion chamber, producing hot gases that are forced out through a nozzle. This expulsion creates a strong push in the opposite direction, propelling the rocket upward. Unlike airplanes, rockets can function in the vacuum of space because they carry both fuel and the oxidizer needed for combustion. This allows them to travel beyond Earth's atmosphere and into outer space.

Rocket propulsion works on the principle of action and reaction, described by Newton’s third law of motion: for every action, there is an equal and opposite reaction. In simple terms, a rocket expels gas out of its engines at high speed, producing thrust that pushes the rocket in the opposite direction. Rockets carry both fuel and oxidizer, allowing them to operate in space where there is no air. By burning this propellant, they create powerful bursts of gas, enabling them to lift off and travel through the atmosphere and beyond, achieving the high speeds necessary for space exploration.
