Question

How does Newton’s 3rd Law of Motion account for the lift of an airplane wing?

A) The shape of the wing lowers gravity on the plane.
B) The shape of the wing increases the density of the air, so it is heavier than the wing.
C) The air follows the curve of the wing and is thrown downward.
D) There is less pressure on top of the wing than there is below the wing.

Answer 1

When airplane moves through the air, the streamlines are closer together above the airplane than they are below it. The air in the region above the wings moves with faster speed than the air below. This difference in speed makes the pressure in the region above the airplane lower than the pressure below the airplane. This results in giving a dynamic lift to the airplane
