Why do Kites fly?

The types of forces that function in the case of the things that are flying are lift, drag, thrust and gravity. The lift is produced by the vacuum on the top of the surface of airfoil. The air passing on the top of the flying object moves rapidly than the air at the bottom of it. The fast air that is travelling on the top equalizes the gravitational force. The air present on the kite shows a friction drag and makes it to move chaotically with the wind. It gets carried away by the wind haphazardly until the string balances the frictional drag force.
If the air is flowing at the bottom of the kite, it lifts the kite upwards due to the change in the momentum. The air that is moving fast on the top of the kite creates little pressure and the air that is moving slower below the kite creates more pressure. This pressure makes the kite to fly up. The length of the string will provide the lift-to-drag ratio and the kite stability which will create more drag.
The flight of a kite is influenced by thrust, drag and gravity. Drag is created by resistance of the wind on the surface of the kite and it also results from the turbulence behind the kite. The weight of the kite creates a force towards down called as gravity while thrust or power to lift up the kite is provided by the wind. The successfully flying kite will have more thrust to reduce the drag and gravity very much.
The forces that are responsible for the flight of the kite like lift, drag, gravity and thrust created by the wind will concentrate at a place called the center of the pressure. This center place which is called tow point is the site where the string is tied to. The attachment of the string to the kite at different places can change the extent of lift created. The change in lift can be changed by changing the angle at which you fly the kite. To make the kite to fly in the wind, it is held up in a certain angle.
