1.
buoyancy; buoyant force
The upward force exerted by a fluid on an object immersed in it. A fundamental concept in physics, also used more broadly to describe the ability of something to float.
A physics term that learners encounter in science contexts. The concept is explained by Archimedes' principle: an object submerged in fluid experiences an upward force equal to the weight of the displaced fluid.
