Bernoulli's Law describes the physics of fluid dynamics, and in the context of air traveling over a wing, it is centered around the relationship between the speed of airflow and pressure. According to Bernoulli's principle, as the speed of a fluid increases, its pressure decreases.

When considering the shape of a wing, or an airfoil, air travels over the upper surface at a higher velocity compared to the lower surface. This increased velocity above the wing leads to a reduction in pressure above the wing. The difference in pressure between the higher pressure below the wing and the lower pressure above generates lift, which is crucial for an aircraft to ascend and remain airborne.

In summary, the phenomenon where air travels faster over the upper surface of the wing, resulting in lower pressure, is a direct application of Bernoulli's Law and is fundamental to understanding how lift is produced in aviation.
