Bouyancy

Bouyancy is the ability of an object to float determined by the Bouyancy Force.

Referring to Archimedes principle;

Bouyancy Force = weight of displaced Fluid
                          = apparent loss in weight after the object is fully or partially submerged
                          = specific weight x volume of fluid displaced
                          = volume of fluid displaced equals to the volume of object submerged

specific weight    = density x accelerated gravity
                          = Unit (Newton over meter cubic)

Thus; Bouyancy Force = density x accelerated gravity x volume
                                    = Unit (Newton)
