Archimedes' principle

 

 

The Archimedes’ principle is a force which is applied to a body immersed in a fluid subject to a gravitational field. So any immersed body in a fluid at rest, is subject to a vertical strength, from the bottom up and it’s opposed to the mass of the fluid’s volumes that are moved. This force is called the “Archimedes’ principle”.

 

Indeed, if we consider a cube subject to the strength of pesanteur Fp  and immersed in water, it will be subject to another strength FA, the Archimedes’ principle which is opposed to the strength of pesanteur. According to the density of the cube, for an equivalent volume, the strength Fp  won’t be the same contrary to the strength FA which won’t change. The cube will float if  FA is superior to Fp and will sink if FA is inferior to Fp .
