The energy of an object is its capability of producing a force that can do work and also its capability of transferring heat. When an object does work on another object, the former’s energy (its capability of doing work) decreases and the latter’s energy increases, by transferring it.' 495: 1274: 1169: 928: 227: 317: 1671: 725:"Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy." 767:
I believe that the energy would be considered to be stored in the gravitational field itself. In general relativity, spacetime has self-interaction. For example, it is possible to create a black hole from gravitational waves alone; the black hole would have mass and thus energy. However, I'm not sure

It is obvious to most people which sense is meant with a bit of context. To be clear, if you want to make a case for removing this material, you need to cite people who are saying it's a problem or that entropy is not an important concept for a generalized understanding of energy. Can you point to

In a nutshell, the current lede is intended to provide three items – i.e., work, heat, and light – that exemplify readily comprehended types of energy, assuming light indeed is a form of energy, as is currently debated by mainstream physicists. Point of trivia: Cutting-edge quantum physicists have

What? Entropy having a distinct sense in statistical mechanics doesn't negate the relevance of using the word for its sense in thermodynamics. It is perfectly justified to include summary discussions of related subjects in this way, as they are often needed for a holistic understanding of a

2. There are at least two independent interpretations of entropy: one from the subjective identification of the number of micro-states in a macro-state (whatever they are!), and one from the thermodynamics of an irreversible process. Neither can be deduced from the
699:. By the way, I don't think it was such a good idea to capitalise "joule" in the infobox. That's a sentence fragment, not a sentence, and it would be better to show the correct capitalisation for this unit name rather than correct sentence capitalisation. Compare 1097:
The whole point of the “forms” of energy section is to list different forms that don’t go down to the most basic forces and energy. ATP is a lot more complex than your regular old energy stored in chemical bonds, even IF that’s what it’s entirely made up out of.
1891:
And there's my problem. "Sources" use entropy in two totally incompatible senses. That tautology should be argued out in an Entropy forum, not here. We should be smart enough to see the elephant in the room and avoid references to such a challenged concept.
1044:
I think Biochemical should be added as another form of energy. It’s different from chemical energy in that it’s unique to living creatures and that’s the main way living things even use energy. There is even a whole field in this called Bioenergetics.
1712:
Entropy is one of two components of free energy, a key idea of chemical energy, and is also related to several aspects of thermal energy. It also relates to multiple aspects of thermocdynamics in general (see several previous talkpage discussions).

The lack of capital letters at the start of each section of text in the table is bothering me, however I can't see how to edit said table as when I click on the pencil icon the text from the table is not displayed.
955:
Hi, I would like to propose an edit so it would make the concept of energy easier for people to understand. I believe this is an accurate description of energy, and it would help people understand physics better.

Au contraire—as it pertains to site policy, we use words the way sources use them, so please keep that in mind before any further edits based on your very particular perspective on how language must be be used.

The speed of sound in steel, copper, etc, as Knowledge (XXG) articles explicitly-state, is *drastically* faster than it is in air, and both of those are crystalline-solids.

By that logic elastic potential energy is just chemical energy then since it stored in the intermolecular bonds. Or the chemical bonds are just electric potentials etc.

Most likely not! Its increased potential energy will be achieved by converting energy of some other form, so the total energy of the space ship might remain the same.

Supporting a challenge to a Wiki article by quoting another Wiki article is nonsense. Energy is a clearly identified physical property. Entropy is not.

if people really talk about it, since energy in GR is not well defined. I'm speaking as a layman on the topic so take what I say with a grain of salt.
2083: 436: 85: 2098: 2063: 541: 805:'s recent edit summary asserts that "light is a form of energy," but it's more precise to say light, as we ordinarily encounter it, is a form of 389: 1730:

When people think of releasing chemical energy they think of something crude like a combustion reaction or something. Not metabolization.

Will a space ship increase in mass if it gains potential energy when raised from one circular orbit to a higher, slower circular orbit?
