- 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.

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.

When the weight of the fluid displaced by the object is more than the object’s weight, then the phenomenon is known as positive buoyancy. In this case, the object will float on the surface of the fluid.
When the weight of the fluid displaced is less than the object’s weight, it is called negative buoyancy. In this case, the object will sink.
When the weight of the fluid displaced is equal to the object’s weight, it is called neutral buoyancy. In this case, the object the object neither sinks nor rises. It will be suspended in the fluid.
Buoyancy (/ ˈbɔɪənsi, ˈbuːjənsi /), [1][2] or upthrust is a net upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
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.
Sep 12, 2022 · There is an upward force, or buoyant force, on any object in any fluid (Figure \(\PageIndex{2}\)). If the buoyant force is greater than the object’s weight, the object rises to the surface and floats. If the buoyant force is less than the object’s weight, the object sinks.
Aug 16, 2021 · Buoyant force is the net upward force on any object in any fluid. If the buoyant force is greater than the object’s weight, the object will rise to the surface and float. If the buoyant force is less than the object’s weight, the object will sink. If the buoyant force equals the object’s weight, the object will remain suspended at that ...
Sep 28, 2018 · The term buoyant force refers to the upward-directed force that a fluid (either a liquid or a gas) exerts on an object that is partially or completely immersed in the fluid. Buoyant force also explains why we can lift objects underwater more easily than on land.
