'''Buoyancy''' is the upward [[force]] acting on an object that causes it to float. For a floating object, the [[weight]] of the fluid displaced by the object equals the weight of the object. The force acting on a totally submerged object is the difference between the mass of the fluid displaced and the mass of the object. If the force is less than the [[mass]] of the object, the object will sink.
