Rocket

A rocket is a device that generates thrust by burning a chemical fuel and directing the exhaust in a particular direction. Conservation of momentum requires that the momentum of the exhaust be balanced by the momentum of the rocket itself, accelerating the rocket via reaction force.

Rockets have existed since the 13th century in China with simple black powder rockets used as flares, weapons, and fireworks. Modern rocketry, however, began in the early 20th century, spearheaded by Konstantin Tsiolkovsky, Robert H. Goddard, Wernher von Braun and Sergei Korolev.
