theories of stability and buoyancy
Theories of stability and buoyancy explain how objects float or remain upright in a fluid. Buoyancy arises from the fluid's supporting force equal to the weight of displaced fluid, making objects float or sink depending on their density. Stability refers to an object’s ability to return to its equilibrium position after tilted; it depends on the shape and center of gravity. A stable object, like a boat or a paperclip on water, naturally returns to balance after being disturbed, while an unstable one tips over. These principles are fundamental in designing ships, submarines, and understanding natural phenomena related to fluids.
