Archimedes' principle
Buoyancy principle in fluid dynamics / From Wikipedia, the free encyclopedia
This article is about fluid dynamics. For the algebraic axiom, see Archimedean property.
Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.[1] Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.[2]
