Why do we weigh less in water?

This article I am writing all based on how I understood the topic .


The question is very clear . Take any object whether it is living or life less ( like stones ) . Weigh them before dipping in water . Note down the reading . Now dip it in water . Now weigh it inside the water .


When we take down the reading , we observe that the weight is lesser compared to what it was outside the water .


There is no deformation . But weight is less . HOW ???


This is called buoyancy . This is the upward force exerted by water .


Now think we droped a stone in a bucket full of water . Now what happens ? Some amount of water gets spilled outside the bucket .


That means some force was there which was responsible for the spilling of water outside . This force is buoyancy , the upward force exerted by water .


Immersion of an object depends on its density . If the object is denser than water , it sinks . If it is lighter then it floats .
