Rocket engine nozzle

A rocket engine nozzle is like an let-shaped part that controls how fast the exhaust gases coming out of the rocket engine move. When they move faster they create more thrust which helps the rocket go faster. The nozzle is like a big pipe that the hot gas comes out of and the nozzle is shaped like a bell with a narrow opening at the end. The shape of the nozzle is important because it changes the speed of the exhaust gases and this helps the rocket fly faster.
