In physics and other sciences, energy is described a scalar physical quantity that is a property of objects and systems which is conserved by nature. Energy is often defined as the ability to do work. But what is that physical quantity really? What is this entity that is all matter in the universe?

That's a good question, one that I don't think can be answered. Physics is constructed of a number of concepts that fit together well and presumably map to something in the physical universe but we don't deal with the reality, the physical universe; we deal with the concepts we create. We manipulate shadows of the physical universe. The number manipulated by physicists that we call "energy" probably refers to an actual something in the universe. But what, I don't know. I tend to think this particular area is more of a philosophical area than a scientific one. Funny, I just brought energy up in a discussion on this sort of thing (i.e. the relationship of mathematics to the natural sciences to the physical universe, etc) in another forum, where I noted:

Energy is a tremendously useful notion, a truly extraordinary concept. But what, if anything, it corresponds to in the physical universe, I don't know.

I've had difficulty with making this connection in the past, particularly in discussions with people who tend to like statements to the effect that "everything is made of energy" or some such idea. I attempt to explain that energy is merely a concept, a mathematical device for bookkeeping that allows us to make sure physical systems obey a rule that the universe seems to follow. At best it's a description of a potential for a certain something to happen, given that rule. The popular conception of energy as some sort of substance that flows between objects has little basis; the "energy beings" of Star Trek don't have much of a leg to stand on. But of course this just highlights the question of what our mathematical concept--"energy"--is describing in the physical universe. How do concepts map onto the physical reality? I understand the temptation to ignore the disconnect or pretend it doesn't exist. Certainly doing so has no effect on our ability to use the law. But it is worth thinking about, if only for unscientific reasons.

Would it be reasonable to state it is the amount of universe that coincides in the same general locality?

And that is?

The universe seems to be a potential. I suppose this is similar to what Startraveler said and it is a conceptual, rather than physical, quality. So it doesn't answer your question. As Startraveler stated from the first, it's possible that question may not have an answer.

You may as well ask what Vacuum is made of, or what color is gravity?

Energy is matter that has not become solid yet...???

No it's not the samething, energy has a true nature. It exists as something.

Energy is a generic term for any of a hundred or thousand different physics items. There is Kinetic Energy which is mass times velocity, but is not the mass or the velocity, but the result of both together. There is Potential Energy, which is due to the acceleration due to Gravity. There is the strong atomic force and the weak atomic force. All can be measured as energy.

There is not a generic Energy particle. If what you are talking about it radiant energy, such as visible light, then it exists as "packets" of energy in a nearly weightless particle.

Does magnetism have a particle? Does gravity?

Yours is not a simple question and certainly does not have a simple answer.

It is important to realize that all of physics is a human construction. It is however a system we have constructed that describes the physical world down to a t. Energy is just a numerical quantity that always remains the same in any given reaction no matter what it is. Thats basically all you can say about it.

So in other words, the term "energy" simply describes a force, and not a "thing", as does the term "gravity"? Hence, there is no actual.. "energy" itself.

its a ion of an atom that migrates into protons or netron both actualy and the protons win . when they are out numbered even just by one ion it can change by surrounding atoms that attract that outnumbered eons in an atom or something like that protons are usually a sufficiant enough answer yes? heck im guessing but im not at all uneducated in the chemical wedding of positives and negatives , postives out number [ protons] therfore making the connection of surrounding atoms ecepting the compnents of the subconscuious blah blah blah,.. yeah some one take over here. lol

Abecrombie
or example + += +
+ -= + or negative depending on surrounding atoms holding the most + usualy connecting creating some kind of energy.

im not a rocket scientist but i do want off of planet earth so i read a bit . lol.

I would say that "energy" in general doesn't exist per se. It is merely a way to quantify and calculate action and reaction in a physical universe. Much like numbers, they don't actually exist, they are just a way to describe an amount.

That's electricity, one kind of many kinds of energy

Does that description match with e=mc squared? Mass definitely seems to exist and it's described as only a different type of energy.
