BUOYANCY :When an object is immersed in a liquid, it exerts an upward force on the object, this phenomenon of upward movement is called Buoyancy.
The upward force exerted by the liquid on the object immersed in it, is called upthrust or buoyant force. The magnitude of buoyant force depends on the density of the liquid.
- If the buoyant force applied by a liquid on an object is greater than the weight of the object, then the object will float in that liquid.
- If the buoyant force is less than the weight of the object will sink in that liquid.
- The magnitude of buoyant force depends on the density.
