Bernoulli’s principle illustrates the relationship between movement and what other physical property?

Bernoulli’s principle describes how the pressure of a fluid decreases as its velocity increases, establishing an important relationship between fluid motion and pressure. According to the principle, in a steady, incompressible flow with no friction, the sum of the pressure energy, kinetic energy (due to the fluid's velocity), and potential energy (due to elevation) remains constant along any streamline.

This principle helps explain various fluid dynamics phenomena, such as lift in airplane wings, where the air moves faster over the top surface than beneath, resulting in lower pressure above the wing and generating lift. The key takeaway from Bernoulli's principle is that as the fluid's speed increases, the pressure must decrease, which illustrates the direct relationship between the dynamics of fluid movement and its pressure.

The other options relate to different physical properties that do not directly contribute to the relationship illustrated by Bernoulli’s principle in the context of fluid flow.
