Is there a simple source to understand Archimedes principal?

I do not know :) Think about the fact that as much volume you enter into a liquid, be it a solid ( for example, a brick ) , as much liquid volume has to go out ( intuitively speaking ) . read more

Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid it displaces. Specific gravity is the ratio of the density of an object to a fluid (usually water). read more

Archimedes' principle, principle that states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principle applies to both floating and submerged bodies and to all fluids, i.e., liquids and gases. read more

This is something related to Archimedes', but I do not believe this is the actual principle you are searching for, as that force is Archimedes' force. However, it comes into my mind that you may refer to something called the hydrostatic principle. read more

In physics, Archimedes’s principle says that any fluid exerts a buoyant force on an object wholly or partially submerged in it, and the magnitude of the buoyant force equals the weight of the fluid displaced by the object. read more

Archimedes' principle is named after Archimedes of Syracuse, the first to discover this law.When he did, he ran naked out of his bathtub. Archimedes' principle relates buoyancy to displacement. read more
