උත්ප්ලාවකතාව

The forces at work in buoyancy. The object floats at rest because the upward force of buoyancy is equal to the downward force of gravity.

උත්ප්ලාවකතාව, (ඉංග්‍රීසි:  Buoyancy).

"වස්තුවක් අර්ධ වශයෙන් හෝ පූර්ණ වශයෙන් තරලයක (ඝන,ද්‍රව,වායු) ගිලී පවතින විට එම වස්තුව මගින් විස්ථාපනය කරනු ලබන තරලයේ බරට සමාන උඩුකුරු තෙරපුම් බලයක් තරලය මඟින් වස්තුව මත ඇති කරයි."

ආකිමිඩීස් නියමය

A metallic coin (an old British pound coin) floats in mercury due to the buoyancy force upon it and appears to float higher because of the surface tension of the mercury.

The Galileo's Ball experiment, showing the different buoyancy of the same object, depending on its surrounding medium. The ball has certain buoyancy in water, but once ethanol is added (which is less dense than water), it reduces the density of the medium, thus making the ball sink further down (reducing its buoyancy).
