The physics of airplanes

This passed weekend I flew to Houston for a volleyball tournament and of course I thought about physics! Physics has a lot to do with the flight of a plane, especially forces and the forces of air on the wings of the plane. As air follows the upper surface of a wing, it gets bent downward because the surface is curved but also because the leading edge is tilted up. To bend the air downward, the wing has to exert a force on it (Newton's first law). With being in the low-pressure zone, above the wing and the higher pressure below it, the air exerts an upward force on the wing which causes it to lift up.
