@zolamir: A fan is determined to get Speed to visit Nepal! Should he go this year? #ishowspeed #nepal #travel #fan #speed Airplane lift comes from the pressure difference created by Bernoulli principle and Newton third law. The airfoil shape is curved on top so air travels faster there, creating lower pressure according to Bernoulli. Meanwhile, the wing is angled to deflect air downward, which generates an upward reaction force on the wing per Newton. Both effects work together. At higher speeds or greater angles of attack, the wing diverts more air downward and creates a more significant pressure gradient between the top and bottom surfaces. It is not just about the air shape though, it is the actual momentum exchange between the air mass and the wing surface that keeps the plane airborne throughout the entire flight.
