Upthrust:

● An object that is partly, or completely, submerged experiences a greater pressure on its bottom surface than on its top surface. ... This force is called upthrust .

● An object in a fluid is displacing some of the fluid. The upthrust force is equal in size to the weight of the fluid displaced by the object.
