Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it, allowing the object to float or sink depending on its density relative to the fluid. This principle is governed by Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

In finance, 'float' refers to the amount of money represented by checks that have been written but not yet cleared by the bank, allowing for temporary dual availability in both the payer's and payee's accounts. In computing, 'float' is a data type used to represent real numbers with fractional components, crucial for precision in numerical calculations.

Density is a measure of how much mass an object or substance has in a given volume, often expressed in units like kilograms per cubic meter or grams per cubic centimeter. It is a fundamental property used to characterize materials and can affect how substances interact, float, or sink in different environments.

Archimedes' principle states that any object, wholly or partially immersed in a fluid, experiences an upward buoyant force equal to the weight of the fluid displaced by the object. This principle is fundamental in understanding buoyancy and is crucial for applications in fluid mechanics and engineering, such as ship design and hydrometry.

Archimedes' principle

Buoyant force is the upward force exerted by a fluid that opposes the weight of an object immersed in it, ensuring that objects less dense than the fluid will float. This phenomenon is described by Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
