Why Airplane Fly?
This is a question that my son asked a few hours ago for our house is a few minutes drive going to the airport and the airplane passes just in our roof. It is quite noisy but we are used to it. When we bought this unit in one of a big subdivision here in our place we really don’t know that the airplane passes by in this area going to landing but as years pass bye we are already used to it. That’s why now my son is now big enough he ask me this kind of question why the airplane fly and what makes an airplane fly.
I told to my son that in order to overcome the Earth’s gravity and rise into the air, the airplane must be acted on by lift force. This is supplied mainly by the craft’s wings. The cross section of a wing is designed so that the angle at which the wing meets the causes the air to flow more rapidly past the upper surface of the wing than the lower surface. As a result, air pressure is lower above the wing than below it, resulting in lift.
My son was satisfied with my short explanation and good enough that I have a little knowledge about this why the airplanes fly.
