The wing of an airplane is basically an airfoil designed to provide lift as a reaction to the force on the wing, upward. But how can an inverted wing provide lift in the same direction?

Centrifugal (away from center) force is the force that pulls something outwards when it travels along a radius, but what is pushing it out... Nothing. Inertia wants to keep that something traveling in a straight line but there must be another force keeping it in that radius. The centripetal (towards center) force is that force. So in short, when you go around a corner in a car, you don't push on the door, the door pushes on you. Do you agree?
