Question

An airplane wing is designed to make the air move

Answer 1

An airplane wing is designed to make the air move  faster over the top than under the bottom. (c)  They do this by making the top of the wing curved and the bottom flat, so the air that flows over the top has farther to go.

It turns out, according to a scientist named Bernoulli, that air exerts lower pressure when it moves faster. So if it moves faster over the top of the wing, then there's less pressure on the top of the wing and more on the bottom, and the wing thinks there's a force that's LIFTING it . . . very convenient and useful if the wing is part of an airplane !
