What is the displacement of water downwards

 
 

But Archimedes did not stop at describing repression.
He investigated the phenomenon further. He noticed: Not only things that submerge displace water, but also things that float.
The deeper a floating object is immersed and the larger its volume, the more water it displaces.

Why does cork float?

 

All things that are immersed in a liquid experience a so-called "buoyancy" through it. This means that the liquid pushes the body upwards, it counteracts the force of gravity.

 

If you dip a cork under water with your hand, you can feel the force of the buoyancy. After letting go, the cork will snap to the surface of the water.
The buoyancy makes the corks bundled here float because cork has a lower density than water.
All objects with a lower density than water float - regardless of their shape.

The principle of Archimedes

 

In his investigation of displacement and buoyancy, Archimedes came across the following principle: The buoyancy that a body experiences is exactly as great as the weight of the liquid that it has displaced.
