The buoyant force is a force which produces and upward pressure on a fully submerged or partially submerged object o the surface of water to make it float.
<h3>Floating</h3>
Floating means staying on the surface of water without getting drowned in the water due to the differences in forces from both the sides of the surface of water.
The lower the mass the higher the buoyant force applied on the object for its floatation. The water with low mass results in higher upward pressure that will help a person to float on the surface of the water easily.
