In general terms, the substance of which physical bodies are composed is known as matter, which has elementary particles and possesses properties such as inertia, gravitation and extension.
The word matter, both at the request of physics and philosophy, is the term used to refer to those issues inherent to objective material reality, because matter is considered as that which will form the sensitive part of objects that can be seen and detected through physical means since they occupy a certain space, they can be seen, touched, felt, measured, among other possibilities.
So, the three characteristic properties of matter are: that it occupies a certain place in space, that it has mass, and that it lasts in time.
Likewise, in common language the term matter is used almost daily when you want to allude to a theme or matter.For example, in the discussion that can take place within a political party, the topic of the next elections is a matter that will appear in the index of matters to be discussed when the next party meeting is held.
But on the other hand and in an academic context, the term subject will refer to a subject. Social Sciences, Mathematics, Language and Literature, Biology, History, Civic Instruction, Geography, among others, correspond to what in the educational environment is generally called study subjects.
On the other hand, when someone talks about Gray matter, is not referring to any type of matter plausible to receive a certain color, but in the context of anatomy, gray matter is called that matter that covers and forms part of our central nervous system and which is in charge carrying out the main brain functions. It was given that name because it has a greyish tone.
And on the other hand, the other widely known and widespread type of matter is raw material, that refers to each of the materials extracted from nature and that serve to transform it and later create consumer goods. According to their origin they are classified as vegetable, animal and mineral, such as wood, skins, iron, among others.
