Matter

In physics, each of the bodies around us ( a grain of sand, stone, moon) is called the physical body or just body.

The physical body - it’s a pen, a leaf, a drop of water, a tennis ball, etc. Everybody has the shape and volume.


Let’s make another thought experiment. Think about piece of wood or paper (or any other material you like). Divide it into two parts. Then divide it one more time. Continue division until you get the smallest piece possible. At some point this division will stop because you will get indivisible particle. This indivisible particle is called atom (“atomos” in Greek means indivisible).

Each element has its own atom. Atom of iron is different from atom of gold; atom of coal is different from atom of copper.
