👉 The term "fluid" in the context of fluid dynamics refers to a state where a substance, such as a liquid or gas, can flow smoothly without resistance. It describes a medium that moves continuously and without interruption, often characterized by its ability to adapt to the shape of its container while maintaining a consistent flow. This concept is crucial in understanding various natural phenomena, from the movement of water in rivers to the flow of blood in the human body. Fluid dynamics explores how forces like viscosity, pressure, and gravity affect this fluid motion, helping us to predict and analyze the behavior of fluids in different scenarios.
