You can model buoyant force as a change in net weight ( though it's more physical and more common to model buoyancy as a separate force ); but it's incredibly uncommon to model buoyant force as a change in mass.

Note that since buoyant force increases as " R 3 " and Stokes'drag increases as " R ", the terminal velocity increases as " R 2 " and thus varies greatly with particle size as shown below.

If the object is supported so that it remains at rest, for instance by a cable from which it is hanging, or by a surface underneath, or by a liquid on which it is floating, there is also a support force in upward direction ( tension force, normal force, buoyant force, respectively ).

Notwithstanding the apparent strength of the game, G . R . Tainton, a former secretary of the QFA, declared in July 1937 that " Soccer football nowadays is not the buoyant force in Brisbane sport it was a decade ago . . .
