WebWhen an airplane is flying straight and level at a constant speed, the lift it produces balances its weight, and the thrust it produces balances its drag. However, this balance of forces … WebJun 18, 2024 · Summary. Students revisit Bernoulli's principle (presented in lesson 1 of the Airplanes unit) and learn how engineers use this principle to design airplane wings. Airplane wings create lift by changing the pressure of the air around them. This is the first of four lessons exploring the four key forces in flight: lift, weight, thrust and drag.
