Etymology

The word "physics" comes from the Greek word "physikos", which means "of nature".

The word "physics" was first used in English in the 15th century. It was used to refer to the study of nature, as opposed to the study of the human mind or the social world.

The root of the word "physics" is the Greek word "phusis", which means "nature". The word "phusis" is derived from the Proto-Indo-European root *bʰuH-, which also means "nature".

So, the word "physics" literally means "the study of nature". This is a reference to the fact that physics is the study of the fundamental laws of nature, such as the laws of motion and the laws of thermodynamics.
