Day 3 (3/21)

The Bernoulli effect is where the wing is moving through the air and some of the air is forced to go over the top of the wing and speed up, because free air doesn't compress so it speeds up to move over the (bigger) top of the wing. Higher wind speeds means that there is less air pressure, because fast moving air can only exert pressure in the direction it is moving in. The air that moves under the wing moves slower and slower air has a higher pressure, so it lifts the wing up.

The Newtonian effect is where, due to the angle of attack the air skips off of the bottom of the wing and therefor pushing it up.

The Circulation theory is a combo of the two. The air bounces off of the bottom of the wing and some of it is forced in front of the wing.
