<P> Archimedes ' principle states that the upward buoyant force that is exerted on a body immersed in a fluid , whether fully or partially submerged , is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid . Archimedes ' principle is a law of physics fundamental to fluid mechanics . It was formulated by Archimedes of Syracuse . </P>
