In this chapter you will learn the Law of Archimedes.
This is a famous physics law that explains, among other things, why a heavy metal ship floats while a much less heavy solid piece of metal actually sinks.
The famous Greek inventor Archimedes devised this law when he was in the bath, and he suddenly got inspiration when he saw the water rise from his bath.
That is why he hurriedly ran through Athens to his laboratory to prove with experiments and calculations that his thought was good.
While running, he shouted loudly: Eureka !! Eureka !! which means: I have it !! I've got it!!
Archimedes distinguished 3 different situations:
Sinking: - then the object sinks into the liquid.
- the entire object is immersed in the liquid.
Floating: - then the object floats somewhere between the bottom and the surface.
- the entire object is immersed in the liquid.
Hovering: - the object floats on the surface.
- a part of the object protrudes above the liquid.
