Law 1: Upthrust
Upthrust (U) = Weight of fluid displaced
The upward buoyant force exerted by a fluid on a submerged object is equal to the weight of the fluid that the object displaces.
Law 2: Floating Object
Weight of object = Upthrust
An object floats in a fluid if the upward buoyant force (upthrust) is equal to its weight.
Law 3: Partially Submerged
Volume submerged / Volume of object = Density of object / Density of fluid
When an object floats partially submerged, the ratio of submerged volume to total volume equals the ratio of the object's density to the fluid's density.
