Bernoulli's principle

Fast flow, low pressure

Bernoulli's principle states that as the speed of a moving fluid increases, its pressure decreases.

This relationship explains how airplane wings generate lift—air moves faster over the curved upper surface, creating lower pressure above than below.

The principle applies broadly in physics and engineering: The Bernoulli effect keeps the shower curtain clinging to your leg.
