buoyancy; lifting force
Technical term for the upward force exerted by a fluid, or more generally the ability to float or be lifted. Used in physics, engineering, and sometimes metaphorically.
The ship floats on the water due to buoyancy.
This material is light and has high buoyancy.
Compound of 浮揚 (ふよう, 'floating, lifting') and 力 (りょく, 'force'). The exact historical derivation is uncertain, but the word follows standard Sino-Japanese word formation patterns.
