What happens to the atoms in the cloth and ruler to cause this damage?

When a cloth and a ruler come into contact, friction generates heat, which can cause the atoms in both materials to vibrate more intensely. This increased molecular motion can lead to the breaking of bonds between atoms, resulting in wear or damage to the surface of the materials. Additionally, if the friction is strong enough, it can cause microscopic particles to be abraded from the surfaces, further contributing to the degradation of both the cloth and the ruler.
