What is the largest contributor to creation of lift? Bernouli or Newton? In all my readings Bernouli has always been stressed while they merely mention Newton's third law. NASA's website says that the creation of lift is flawd in theories and common misinterpretations. They say that as the fluid is bent Newtons 3rd law is the primary contributor as the air flows over the top of the wing it flows down with the curvature and since it flows down it causes the reaction to go up. This is a new theory for me and is different from the old hand out the window of a car scenario. Anybody know more about this or what they are saying and can bring this further into light.
