Buoyancy - Wikipedia

Learn how to calculate the buoyant force of an object immersed in a fluid using Archimedes' Principle and the formula Fb = PA, where P is the pressure, A is the area, and h is the height of the immersed part. See solved examples and a customizable course on physics formulas.

14.6: Archimedes' Principle and Buoyancy - Physics LibreTexts

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.

Archimedes' principle | Description & Facts | Britannica

Buoyant force is the upward force applied by a liquid on an object that is half or completely immersed in it. It is the result of the difference in weight of the object and the liquid. Learn how to calculate buoyant force, its units, applications and examples in physics.

Archimedes principle and buoyant force (video) | Khan Academy

Buoyant force is the upward-directed force that a fluid exerts on an object that is partially or completely immersed in the fluid. It depends on the hydrostatic pressure, the weight of the displaced fluid, and the shape of the object. Learn how Archimedes discovered buoyancy, how to calculate buoyant force using formulas, and see examples of buoyant force in nature.

14.4 Archimedes' Principle and Buoyancy - OpenStax

The buoyant force comes from the pressure exerted on the object by the fluid. Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top - hence the net upward force. The buoyant force is present whether the object floats or sinks.

10.3: Archimedes' Principle - Physics LibreTexts

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.

Buoyancy - Summary - The Physics Hypertextbook

Buoyant force is the upward force exerted on objects submerged in fluids by the difference in pressure between the bottom and the top of the object. It depends on the density of the fluid, the acceleration due to gravity, and the volume of the displaced fluid. Learn how to calculate buoyant force with a formula and examples.

7.2: Buoyancy - Physics LibreTexts

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).

Buoyancy | History, Science, & Applications | Britannica

The buoyant force, which equals the weight of the fluid displaced, is thus greater than the weight of the object. Likewise, an object denser than the fluid will sink. The extent to which a floating object is submerged depends on how the object's density is related to that of the fluid.
