# What Is a Buoyancy?

Buoyancy is the ability or tendency of things to float in water or air or some other fluid. It's the power of a liquid to keep something afloat. In the world of physics, buoyancy is the upward force, caused by the pressure of fluid, which keeps things afloat. This can occur only in an accelerated frame of reference.

Buoyancy is the ability or tendency to float in water or air. It is an upward acting force which is caused by fluid pressure that opposes an object's weight. If an object is either less dense than the liquid or is shaped appropriately such as a boat, the force keeps the object afloat.
In physics, buoyancy is the upward force on an object produced by the surrounding liquid or gas in which it is fully or partially immersed, due to the pressure difference of the fluid between the top and bottom of the object.
