  2. characterized by liveliness and lightheartedness; "buoyant spirits"; "his quick wit and chirpy humor"; "looking bright and well and chirpy"; "a perky little widow in her 70s"
  3. (buoyantly) in a cheerfully buoyant manner; "we accepted the opportunity buoyantly"
  4. (buoyancy) cheerfulness that bubbles to the surface
  5. (buoyancy) airiness: the property of something weightless and insubstantial
  6. (buoyancy) the tendency to float in water or other liquid
  7. In physics, buoyancy is an upward acting force, caused by fluid pressure, that opposes an object's weight. If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. ...
  8. having buoyancy; able to float; lighthearted and lively
  9. (buoyantness) The state or quality of being buoyant
  10. (buoyancy) the upward force on a body immersed or partly immersed in a fluid; The ability of an object to stay afloat in a fluid; resilience or cheerfulness
  11. (Buoyancy) The ability or tendency to float or rise in a liquid.
  12. (Buoyancy) The upward force exerted on an object in liquid, whether the object sinks or floats. Objects that float are positively buoyant, those that sink are negatively buoyant and those that stay where placed are neutrally buoyant.
  13. (Buoyancy) The tendency of a body to float or rise when submerged in a fluid.
  14. (Buoyancy) The upward force that a fluid exerts on an object less dense than itself.
  15. (Buoyancy) Defined in Archimides' Principle as the amount of upward force acting on a submerged object. The force is equal to the weight of the water displaced by the object.
  16. Buoyancy refers to the power of supporting a floating body, including the tendency to float an empty pipe (by exterior hydraulic pressure).
  17. (buoyancy) The ability for an object to be lifted up, or to float, because of the greater density of the liquid it is in
  18. (BUOYANCY) Degree of floatability
  19. (Buoyancy) 4-channel tape. 1977
  20. (Buoyancy) Flexible sponsons (pontoons / tubes) inflated with air for rigidity.  Ridged sponsons trap air. (1Cubic Meter of trapped air will support 1 Tonne)
  21. (Buoyancy) Flotation materials fitted inside a craft or onto a person to keep the craft or person afloat.
  22. (Buoyancy) Force which enables anything to float. Many boats have built in buoyancy tanks in case of the hull being holed or the boats capsizing.
  23. (Buoyancy) Pronounced As: boins, booyn- , upward force exerted by a fluid on any body immersed in it. Buoyant force can be explained in terms of Archimedes' principle.
  24. (Buoyancy) The capacity to remain afloat
  25. (Buoyancy) The lifting force acting in a fluid on bodies and regions less dense than their surroundings. The buoyancy of hot air--the force that also lifts hot-air balloons--is the main cause of weather-related flows in the Earth's atmosphere. Also see convection.
