Archimedes principle content
The content of Archimedes' principle is that an object immersed in a liquid is subjected to upward buoyancy, and the buoyancy is equal to the gravity of the liquid it displaces. The buoyancy of an object is determined by the density of the liquid and the volume of the liquid it displaces, and has nothing to do with the depth of the object immersed in the liquid, the mass and density of the object and the shape of the object.

Archimedes principle content

Archimedes principle, also known as the law of buoyancy, means that an object immersed in a liquid is subjected to upward buoyancy, which is equal to the gravity of the liquid it displaces, and has nothing to do with the depth, mass, density and shape of the object immersed in the liquid. Mathematical expression: F float =G row = ρ tu g V row, which is suitable for liquids and gases.

Enlightenment of Archimedes' principle

Archimedes wanted to measure the volume of the crown in order to identify whether it was pure gold, but it took him a long time to get the result. Until one day when he was taking a bath, he stepped into the bathtub and found that the water in the bathtub overflowed. Then he wondered whether the volume of an object in a liquid is the volume of water boiled by the object, so there was Archimedes principle behind it.
