Question

define archimedes principle

Answer 1

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.[1]In On Floating Bodies, Archimedes suggested that (c. 250 BC):

Any object, wholly or partially immersed in a stationary fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

Answer 2

Archimedes principle says that if an object is immersed in a fluid the fluid exerts a force equal to the weight of the volume of the fluid displaced by the object.(called bouyant force)
