HOW AIRPLANES WORK

The wing helps the airplane get airborn.The air on the bottom moves slower than the air on the top so it weighs more and pushes the airplane up.

HOW A JET ENGINE WORKS =Air enters the front of the engine and is compresed by a powerful fan.This pressed air is then mixed with fuel.Very hot gases speed out of the back of the airplane pushig the aircraft along.

HOW A PROPELLER WORKS

The propeller of an aircraft is like a huge fan spinning at a very high speed.It works on the air like a wing, pushing the air backwards and pulling the aircraft forward.
