Buoyancy and Buoyant Force: Definition, Examples, and Formula
This equation is also called the law of buoyancy. It gives a relationship between buoyancy and density. As can be seen, the buoyant force is proportional to the density. The factors that affect buoyancy are: The density of the fluid; The volume of the fluid displaced; Acceleration due to gravity; The buoyant force causes objects to float.
