What's the difference between buoyancy and buoyant?

Buoyancy


Definition:

  • (n.) The property of floating on the surface of a liquid, or in a fluid, as in the atmosphere; specific lightness, which is inversely as the weight compared with that of an equal volume of water.
  • (n.) The upward pressure exerted upon a floating body by a fluid, which is equal to the weight of the body; hence, also, the weight of a floating body, as measured by the volume of fluid displaced.
  • (n.) Cheerfulness; vivacity; liveliness; sprightliness; -- the opposite of heaviness; as, buoyancy of spirits.

Buoyant


Definition:

  • (v. t. & i.) Having the quality of rising or floating in a fluid; tending to rise or float; as, iron is buoyant in mercury.
