Fluids

About

In physics, a fluid is a liquid, gas, or other material that continuously moves and deforms under an applied shear stress or external force. Fluids are characterized by having zero shear modulus, meaning they cannot resist any shear force applied to them. This fundamental property distinguishes fluids from solids and other materials that possess structural rigidity. The ability of fluids to flow and adapt to forces makes them essential to understanding various natural phenomena and scientific principles.
