Why do we weigh less in water?
Hey. Looks like you have gained a lot of weight.
Come on.
Let us check your weight.
You weigh 132 pounds.
Alright.
Don't get stressed.
Check your weight in water.
Look. It is much lesser.
Do you know why you weighed less in water?
The answer to this is based on Archimedes Principle.
Not that principal.
Archimedes Principle is a fundamental truth which states that an object fully or partly immersed in a fluid experiences an upward force called buoyant force which is equal to the weight of the fluid displaced by it.
It went over your head, right?
No worries. Let me explain.
Gravity always pulls us downwards.
Hence, the weight of our body always acts downwards whether we are on ground or in water.
However, according to Archimedes Principle, when we are in water, we experience an upward force, that is, buoyant force which is equal to the weight of water displaced by us.
This upward force cancels a portion of our weight causing us to weigh less in water.
