Which physical principle helps explain how lift is accomplished across an airfoil?

Lift generation across an airfoil can be primarily explained by Bernoulli's Principle for Flight. This principle states that as the velocity of a fluid (in this case, air) increases, its pressure decreases. When an airfoil is in motion, the shape of the airfoil causes the air to travel faster over the top surface compared to the bottom surface. According to Bernoulli's Principle, the increased speed of airflow over the top of the wing results in lower pressure above the airfoil, while the relatively slower airflow beneath it maintains higher pressure. This difference in pressure creates an upward force known as lift, allowing the aircraft to rise.

The other principles, while related to mechanics and fluid dynamics, do not specifically explain the process of lift generation in the same way. For instance, Newton's First Law pertains to the inertia of objects at rest and in motion, but does not address the dynamics of fluid movement in relation to lift. Newton's Third Law discusses action and reaction forces, which certainly play a role in flying (as the wing pushes air down and experiences an equal force upward), but it does not fully encompass the intricate relationship between airspeed and pressure needed to understand lift as Bernoulli's Principle does.
