The upward force acting on an object placed in a fluid. The buoyancy force is equal to the weight of fluid displaced by the object. Buoyancy can have significant effects over a wide range of completio [..]

The tendency of a body to float or to rise when submerged in a fluid; the power of a fluid to exert an upward force on a body placed in it.

1713, from buoyant + -cy. Figurative sense (of spirits, etc.) is from 1819.

the power to float or rise in a fluid.

n. Power or tendency to float on or in a liquid or gas.

the tendency of a body or fluid to rise when it is less dense than its surroundings.

The ability of water to support weight allowing an object to float.

(physics) the upward force on a body immersed or partly immersed in a fluid (context, by extension) resilience or cheerfulness

(n) the property of something weightless and insubstantial(n) the tendency to float in water or other liquid(n) irrepressible liveliness and good spirit(n) cheerfulness that bubbles to the surface

Upward force exerted on an object in liquid that causes it to float because the liquid has a greater density than the object (Lesson 13)

the upward force on a free floating or submerged object, independent of the object's weight; gives submerged objects the weightless

The resultant upward forces, exerted by the water on a submerged or floating body, equal to the weight of the water displaced by this body.

The ability or tendency to float or rise in a liquid.

the ability to float, or in more technical terms – the upward forces exerted by a fluid on a body in it.

The resultant upward forces, exerted by the water on a submerged or floating body, equal to the weight of the water displaced by this body.

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 [..]

The propensity of an object to float (positive buoyancy) or sink (negative buoyancy) or to do neither (neutral buoyancy).

The upward force extended by the vertical component of integrated pressure acting on the hull below the waterline; usually calculated as being equal to the weight of the water displaced by the hull.

Ability to float, lifting power when immersed.

The capacity for floating.

Degree of floatability

The purpose of any lifejacket is to make the wearer float, how much floatation each life jacket has - buoyancy - is measured in Newtons, or N.

the degree to which an object floats in a fluid

The capacity for floating.

the ability to float due to an object displacing a fluid medium greater than its own weight. Buoyancy can be controlled by the use of ballast. catenary curtain: a fabric curtain and metal cable struct [..]

The tendency of a body to float or to rise when submerged in a fluid; the power of a fluid to exert an upward force on a body placed in it.

the tendency of a body to float or rise when immersed in a fluid; the power of a fluid to exert an upward force on a body placed in it.

Tendency of a fluid or solid to rise through a fluid of higher density

In meteorology the upward force exerted upon a parcel of air by virtue of the density difference between itself and the surrounding air.

That property of an object that enables it to float on the surface of a liquid, or as in the case with air

An attribute of parcels of fluid (e.g. air) that is less dense than their surroundings and feel an upward force. When a parcel of air at the earth's surface is warmed it can become more buoyant than the surrounding air and start to rise. It will cool adiabatically as it rises, but if the surrounding environment is cooling even faster it will c [..]

The tendency of a body to float or to rise when submerged in a fluid; the power of a fluid to exert an upward force on a body placed in it.
