Buoyancy (/ ˈbɔɪənsi, ˈbuːjənsi /), [1][2] or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column ...

What is Buoyancy When an object is immersed in a fluid, wholly or partially, the fluid exerts an upward force opposite its weight. This phenomenon is known as buoyancy, and the upward thrust is known as the buoyant force. A characteristic of buoyancy is that it determines whether an object will float or sink.
Explore the principles of buoyancy through interactive simulations, learning about fluid density, object volume, and their effects on floating and sinking.
Buoyancy describes the tendency of an object to float or rise in a fluid when submerged; this fluid can be either a liquid or a gas.

Buoyancy is defined as the tendency of a body to float or rise when submerged in a fluid. The resultant force acting on a submerged body by the fluid is called the buoyant force and can be expressed as
