A body floats in a liquid when the weight of the body is equal to the weight of the liquid displaced. Any object immersed in a fluid, whether entirely or partially, is buoyed up by a force equal to the weight of the fluid displaced by the object.
Example of object floats in a liquid ship floating in the water which is a popular example of Buoyancy force.
What is Buoyancy?
We can define Buoyancy as the upward force applied by the fluid on the object or the body when an object is put in or submerged in the fluid.
The unit of the buoyant force is the Newton (N).
