If the relative wind velocity increases, the airfoil will produce what?

Explanation:
Lift on an airfoil grows as the relative wind speed increases, because the dynamic pressure the airfoil faces is proportional to V^2. If you keep the airfoil’s shape and angle of attack the same, higher speed means more dynamic pressure acting on the wing, so it generates more lift. This holds in normal operation; near or at stall, increasing speed won’t keep increasing lift if the angle of attack is too high, and lift can level off or drop. So the airfoil will produce more lift with higher relative wind velocity.
