buoyancy: [noun] the tendency of a body to float or to rise when submerged in a fluid.
What Is Buoyancy? All liquids and gases in the presence of gravity exert an upward force—called buoyancy —on any object immersed in them. If the object is less dense than the liquid or gas, buoyancy will make it float. A cork floats in water because it is less dense than a cork-size volume of water. But it won’t float in air because it is ...
The buoyancy force on an object in a fluid equals the weight of the fluid displaced by that object. As simple as this seems, it is very easy to get confused about this force. The main source of confusion tends to be distinguishing the buoyancy force from the net force on the object (which also experiences gravity).
May 26, 2023 · Buoyancy is the force acting opposite the direction of gravity that affects all objects submerged in a fluid. X Research source When an object is placed in a fluid, the object's weight pushes down on the fluid (liquid or gas) while an upward buoyancy force pushes upward on the object, acting against gravity.

Buoyant Force. Buoyancy is the tendency of an object to float in a fluid. All liquids and gases in the presence of gravity exert an upward force known as the buoyant force on any object immersed in them. Buoyancy results from the differences in pressure acting on opposite sides of an object immersed in a static fluid.
v. t. e. Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. [1] Archimedes' principle is a law of physics fundamental to fluid mechanics.
The buoyant force is the same as long as the object displaces the same amount of fluid. The example below shows what is meant by displaced volume in the buoyancy force equation. Example (2): A rectangular container of ethanol with density \rho_ {eth}=800\, {\rm kg/m^3} ρeth = 800kg/m3 floats in the liquid of density \rho_ {f}=1200\, {\rm kg/m ...
