How kites stay in the air
So how exactly does the kite stay up there? Flying a kite uses the basic principles of lift, weight, thrust and drag, much like any other flying object or toy. The upward force of lift pushes the kite up on a current of air pressure, while the weight of gravity pushes down on the kite towards the Earth’s centre. The moving air currents and pull of the string generate thrust to keep the kite in motion, while drag or resistance is created by the differences in air pressure. To keep the kite airborne, you must keep these four forces in balance.
