Floatation Theory

Floatation Theory explains how a liquid's density affects whether objects sink or float. An object will float if its overall density is less than that of the liquid, which is why a boat made of steel can stay afloat—its shape displaces enough water to support its weight. Conversely, an object denser than the liquid sinks. The theory relies on Archimedes’ principle, stating that a floating object displaces a volume of liquid equal in weight to itself. This principle is fundamental in understanding buoyancy and designing objects like ships, submarines, and even in analyzing natural phenomena involving fluids.
