Buoyancy

Volume Above Surface

Buoyancy is a phenomenon that occurs when an object is submerged in a fluid, such as water or air. Archimedes' Principle states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.

To calculate the buoyant force on an object, you need to first find the weight of the fluid displaced by the object. This can be done by calculating the volume of the fluid displaced and multiplying it by the density of the fluid. The buoyant force acting on the object is then equal to the weight of the fluid displaced.

Buoyancy and Archimedes' Principle have many real-life applications. For example, ships are designed to displace a large amount of water to generate enough buoyancy to support their weight and cargo. Similarly, hot air balloons use the principle of buoyancy to rise into the air, as the heated air inside the balloon is less dense than the surrounding air. The principle also plays a role in the design of submarines, which use buoyancy to control their depth in the water.

The formula for determining the buoyancy according to Archimedes' Principle is defined as:
\(F_b\) \(=\) \(\rho\) \(\cdot\) \(g\) \(\cdot\) \(V\)
\(F_b\): the buoyant force
\(\rho\): the density of the liquid
\(g\): the gravity (Earth's gravity is approx. 9.807 meter/square second)
\(V\): the volume of the fluid being displaced
The SI unit of buoyancy is: \(Newton \text{ }(N)\)
