A wing moves through a fluid, forcing the fluid to deform and flow around its shape.
The equal transit theory claims that air molecules splitting at the leading edge of an airfoil must meet simultaneously at the trailing edge. Because the upper surface is curved, the air must travel faster, creating lower pressure via Bernoulli’s principle.

McLean argues that lift cannot be explained by a single, isolated physical law. Instead, lift is the result of a cause-and-effect loop where pressure fields, velocity fields, and momentum conservation act simultaneously. The Cause-and-Effect Loop

Second, a physics-based approach can help to identify and mitigate potential problems and hazards. For example, a more accurate understanding of the behavior of air around an aircraft can help to prevent stalls and spins. Related search suggestions: (functions

On a lifting wing, a localized low-pressure zone develops over the upper surface, while a higher static pressure zone forms underneath.
