If there are two air molecules when a plane approaches and one goes over the curved top of the wing and the other goes under the wing, why does the top one travel faster? Why don’t they go over the wing at the same speed so the top one ends up slightly further away than the lower one when the plane’s gone?
In: Physics
The angle of the wing applies a force to air that moves under it, increase pressure. Conversely, it lowers the pressure of the air that flows over the wing. According to Bernoulli’s principle, there is a relationship between the pressure of a fluid and it speed. Basically, increased pressure is associated with decreased speed and decreased pressure is associated with increased speed. So the increased pressure of the air under the wing slows it down and the decreased pressure of the air above the wing speeds it up.
