Buoyant force from density and volume¶

Any object, totally or partially immersed in a fluid (i.e. liquid or gas), is buoyed up by a force equal to the weight of the fluid displaced by the object. Also known as the Archimedes principle. The buoyant force vector is directed opposite to the gravity vector.
