The upward force exerted by a liquid on an object immersed in it is known as buoyancy. When you try to immerse an object in water, then you can feel an upward force exerted on the object, which increases as you push the object deeper into the water.
Buoyancy is the same principle used above to compute hydrostatic forces that can be used to calculate the net pressure force acting on completely submerged or floating bodies. These laws of buoyancy, the principles of Archimedes.
- In addition to the downward pull of gravity that supplies a force equal to mg, there will also be an upward buoyant force due to the pressure of the fluid.
- We can determine the strength of this buoyant force on our object by doing the following thought experiment.
- The Buoyancy force may or may not result in the material object floating in equilibrium with no net force acting mean neutral Buoyancy.
