The nozzle of a rocket is pointed downward so that as fuel is ignited, the exhaust pushes downward. Why is this arrangement necessary for a rocket to function properly?

• The rocket is protected from the heat of the exhaust.

• Burned fuel can be collected on the ground.

• As fuel is combusted, the rocket pushes the gases backward and the gases push the rocket forward.

• This allows the rocket to be steered properly.
