Buoyancy
Buoyancy is the net upward force arising from pressure differences over an object in a fluid under gravity. Its magnitude equals the weight of the displaced fluid in the usual hydrostatic model. For example, a fully submerged object can rise, sink, or remain suspended depending on how buoyancy compares with its weight.
