8th Class Buoyancy

        Buoyancy

When an object is immersed in liquid an upward force acts on it, which is called buoyancy. The buoyant force does not depend upon the weight of the object or the shape of the object, it only depends on the weight of the liquid displaced by the object. This principle is applicable to all the object of any density. If the density of the object is more than the density of the liquid, the object will sink. But if the density of the liquid is more than the object, the object will float on the surface of the liquid. On the other hand, if the density of the liquid and objects are equal, the object will float with half part immersed in the liquid.
