Bouyant Forces
Buoyant forces play a fundamental role in fluid dynamics, describing the upward force exerted on an object immersed in a fluid, such as water or air. This phenomenon, rooted in Archimedes' principle, states that an object submerged in a fluid experiences an upward force equal to the weight of the displaced fluid. Understanding buoyant forces is crucial in various fields, from engineering and physics to aquatic biology. This force is not only a fundamental principle in fluid mechanics but also underpins the design and functionality of numerous objects and structures in our daily lives.
