Rocket

A rocket is a vehicle, missile, or aircraft that is propelled by a rocket engine or other form of jet engine that carries its own propellant and expels exhaust at high speed to generate thrust in accordance with Newton's third law of motion. The term rocket can be translated to טיל in Hebrew, Rakete in German, Fusée in French, and Raket in Russian. Rockets are used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration. The first stable rockets were developed in China during the Song dynasty, and the technology spread throughout the world through trade and conquest. Rockets come in a variety of shapes, sizes, and types, but all operate on the basic principle of expelling mass to create thrust. Key components of a rocket include the propellant, combustion chamber, nozzle, and guidance system. Rockets have played a pivotal role in space exploration, enabling humanity to reach the Moon, explore other planets, and launch satellites that have revolutionized global communication and navigation.
