Vortex

A vortex is a spinning, often circular flow of fluid—liquid or gas—that creates a characteristic whirlpool or spiral pattern. Think of how water swirls down a drain or how tornadoes and hurricanes form. The rotating motion causes the fluid to move around a central axis, creating a low-pressure area inside the vortex that sustains the spin. Vortices occur naturally in nature and are also produced by objects moving through fluids, affecting weather, aircraft design, and even sports. They illustrate how rotational forces influence the behavior and movement of fluids in various environments.
