conservation of energy


Also found in: Dictionary, Thesaurus, Legal, Acronyms, Encyclopedia, Wikipedia.

con·ser·va·tion of en·er·gy

the principle that the total amount of energy in a closed system remains always the same, none being lost or created in any chemical or physical process or in the conversion of one kind of energy into another, within that system.

conservation of energy

[kon′sərvā′shən]
Etymology: L, conservare, to preserve
(in physics) a law stating that in any closed system the total amount of energy is constant. It is superseded by the special relativity equation e = mc2, but it is still applicable in the chemical process.

conservation of energy

The principle according to which energy cannot be created or destroyed, but is transformed into other forms.
See also: energy

conservation of energy

general principle that the total energy of a system (object or body) and its surroundings does not change, but varies in its different components.

Here, although the original law of gravity cannot be derived (the value of D may be any constant, certainly including the case that D=2), we already prove that the original law of gravity is not contradicted to the law of conservation of energy, or the original law of gravity is tenable accurately.
4 Deriving the original law of gravity by using the law of conservation of energy
Thus, we already derive the original law of gravity by using the law of conservation of energy.

In reference [6], the examples deriving the improved Newton's second law and improved law of gravity according to law of conservation of energy are discussed.
In reference [6] we also point out: besides law of conservation of energy, all other laws of conservation in physics may not be correct (or their probabilities of correctness are all less than 100%).
The essential reason for the exclusion principle may be invalid is that it does not take into account the law of conservation of energy, and in physics the principles that are not compatible with law of conservation of energy will be invalid in some cases
To link and combine Newton mechanics with law of conservation of energy, as well as the brilliant achievements of modern science and technology, then Newton mechanics can be expanded and developed effectively and successfully in the maximum area.
Because the law of conservation of energy is the most important one in natural sciences, it should play an increasingly great role.
If the law of conservation of energy is choosing as the unique source law, that in principle, all the Newton's four laws can be derived according to the law of conservation of energy; after studying carefully we found that this may indeed be the real case.
