👉 A fluid, in the context of physics and engineering, is a substance that flows easily under applied force, such as gravity or pressure. It can take the shape of its container, making it highly adaptable and versatile for various applications. Examples include liquids like water, oil, and blood, which exhibit properties such as viscosity and surface tension. Fluids play a crucial role in many natural processes and technological systems, from the movement of oceans and rivers to the functioning of engines and hydraulic systems. Understanding fluid dynamics is essential for optimizing performance, efficiency, and safety in numerous fields, including aerospace, automotive, and biomedical engineering.
