Here, &#039;&#039;upward&#039;&#039; means opposite to the direction of the gravitational field.<br /> <br /> For an object floating or sinking in a fluid, the buoyant force plays a role similar to the [[normal force]] that would exist between a pair of dry solid surfaces.<br /> <br /> By the [[Archimedes principle]], the magnitude of the buoyant force is the [[weight]] of the fluid displaced by the portion of the object that is immersed in the fluid.</div>
