Archimedes’ 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. This principle is considered as the basic principle of fluid mechanics. This principle became famous through his words Eureka Eureka ! . These words were produced by him when he invented the theory . Some historians say that he even ran naked through the streets when he discovered it. This theory can be applied on our daily life also. Archimedes’ principle describes how ships float, submarines dive, hot air balloons fly, and many others examples.
This equation itself is used in many fields including purity checking.

Archimedes’ principle tells us about the forces applied to an object by fluids surrounding it. The applied force reduces the net weight of the object submerged in any liquid or fluid. This physical law of buoyancy helps us to understand how ships float in water.
Archimedes’ principle states that: ” The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in an upward direction at the center of mass of the displaced fluid.”
In simple form, the Archimedes law states that the buoyancy force that acts on an object is equal to the weight of the fluid displaced by the object. Mathematically written as:
F= pvg
Where,
F = buoyant force
p =density the fluid
V =submerged volume
g = acceleration due to gravity
