Final answer:
An airplane's wing design prevents a completely stalled condition by using Bernoulli's principle and Newton's third law. The wing's upward tilt and longer upper surface cause air to flow faster over it, reducing pressure on top of the wing and creating lift.
Step-by-step explanation:
The design of an airplane's wing helps prevent a completely stalled condition by utilizing the principles of Bernoulli and Newton's third law. The wing is tilted upward at a small angle, with a longer upper surface that causes air to flow faster over it. This results in a reduced pressure on top of the wing, creating a net upward force or lift. The deflected air molecules also contribute to an upward force on the wing.
