Buoyancy

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

Buoyancy formula

\(\large{ B =  p A }\)

\(\large{ B =  \rho V g }\)

\(\large{ B =  \rho g h A }\)

Where:

\(\large{ B }\) = buoyancy force

\(\large{ A }\) = surface area of object

\(\large{ \rho }\) (Gtrrk symbol rho) = density of the fluid

\(\large{ g }\) = gravity

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

\(\large{ p }\) = pressure

\(\large{ V }\) = displaced volume
