Description: Explain qualitatively the origin of BUOYANCY. Use the vector expression of BUOYANCY. Implement a device to test or exploit the expression of BUOYANCY.

Definition
Buoyancy: Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object.

Archimede's principle: Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.

F_b = - ρ_fluid . V_fluid . g
