The buoyant [[Force]] on an object immersed in a [[Fluid]] is equal to the weight of [[Fluid]] displaced by the object.
The reason why there is a force is because for an object to sink down in a fluid, that fluid needs to be pushed up, meaning gravity has to work double time.

If the [[Buoyancy Force]] is less than the force applied by gravity, the object simply falls slower to the bottom, but if the force is greater than gravity, the object will float.
