They work because of Lift. The upper surface of a wing is curved so that air traveling over it travels a longer distance than the air traveling under it, that produces a vacuum effect, the air pressure is less on the top of the wing and that lifts the plane up. You need forward speed to get that effect, thats what the engines (whether prop or jet) are for. Once you have the lift you can get off the ground at the right speed, and then you have control surfaces for banking left or right, up or down.

Do you mean an airplane? Any elementary school science book can tell you. The answer is too voluminous to be contained into the space available.
