Overview
When an object is immersed in a fluid, it experiences an upward buoyant force equal to the weight of the fluid it displaces. Its apparent weight (immersed weight) is its real weight minus this buoyant force.
💡
Pro Tips
If the immersed weight is negative, the object will float.
Archimedes' Principle states that buoyant force = fluid density × volume × gravity.
Density of fresh water is 1000 kg/m³.

Fun Facts
"A person weighing 70 kg has an apparent weight of almost zero in water because humans are roughly as dense as water."
"Testing apparent weight in water is used to measure body fat percentage."
"The term 'displacement' in shipbuilding refers to the weight of water a ship pushes aside."
