Buoyant Force

An object immersed in water is subjected to two forces:
a. the weight of the object which acts downwards, (It pushes the object down)
b. an up-thrust or buoyant force which acts upwards.(it pushes the object up)


If the force from the weight of the object is greater than the force from buoyancy, the object sinks. 
Weight , W > Buoyant force, Fb ; object sink


If the buoyant force is greater than the force from the weight of the object, the object floats.


Weight , W < Buoyant force , Fb ; boject float
