Archimedes' principle: A body floating or submerged in a fluid is buoyed (lifted) upward by a force equal to the weight of the fluid that would be in the volume displaced by the liquid. Archimedes' principle deals with the forces applied to objects by the fluids around the object.

Archimedes' Principle: Physical law of buoyancy fundamental to fluid mechanics, discovered by the ancient Greek mathematician, physicist, engineer, astronomer and inventor Archimedes, the statement that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weighted of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid
