According to Bernoulli's Principle, as the speed of a fluid increases, its pressure decreases. This relationship is a fundamental aspect of fluid dynamics. The principle can be observed in various scenarios, such as airflow over an airplane wing.

When air moves faster over the wing's top surface, it creates an area of lower pressure compared to the slower-moving air beneath the wing. This difference in pressure generates lift, which is crucial for aircraft to take off and remain airborne.

Bernoulli's Principle highlights the inverse relationship between the velocity and pressure of a fluid. As the speed of a fluid increases, its kinetic energy rises, which results in a reduction of the fluid’s potential energy in the form of pressure. This concept is a cornerstone in understanding a wide range of aerodynamics and is instrumental in the design and function of various aircraft components.
