How
is a Kite Flying?
A kite is an object which is made from a light material stretched over a frame. Due to its light material a kite will lift off the ground and fly when it is tilted into the wind.
A kite is uses wind to make it fly because it is heavier than air. When wind travels over the surface of the kite, it is split into two streams of air. One stream of the air goes over the kite while the second stream goes under the kite.
The upper stream creates an area of low pressure above the kite. The lower stream hits the kite at a shallow angle and creates an area of high pressure.
The high pressure area has a pushing effect while the low pressure area has a pulling effect. The combination of push and pull can creates enough force to lift the kite into the air.
Kites have been known for thousand of years. They are used for military or scientific purposes. Todays kites are much used for leisure and competition.
