Rocket

Rockets accelerate a ship by combusting a liquid or gaseous fuel and expelling the resultant gas at high speed. The ejection of this mass creates an equal and opposite reaction: the rocket and the ship attached to it accelerate on a trajectory opposite to that of the ejected reaction mass.

Rockets can be fueled by using a pump to convey liquid or gaseous fuel from a tank and along a pipe to the rocket.
