Archimedes' Principle

The Archimedes' Principle is the law which establishes that a body immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the body. This upward force which pushed up the body is called "buoyant force". The body will sink if the weight of the water displaced is less than the weight of the body, as it happens when it is a dense object. The law is named after Archimedes of Syracuse, the Greek physicist who discovered it.
