buoyancyBuoyancy is when a liquid applies upward force on an object that is completely submerged or floating.


\(B =  p A  \)

\(B =  \rho V g  \)

\(B =  \rho g h A  \)


\(B\) or \(F_b\) = buoyancy force

\(p\) = pressure

\(A\) = surface area of object

\(\rho\) (Gtrrk symbol rho) = fluid density

\(V\) = displaced volume   

\(g\) = gravity, \(\;9.8 m/s^2\)

\(h\) = height of liquid displaced by a floating object
