In a closed system that is isolated from the outside world, the total energy within it remains constant. It can also be seen as a modified form of the first law of thermodynamics*. This form of the law of conservation of energy was established as a result of the research of three men: Mayer, Helmholtz, and Joule. According to the theory of relativity, energy and mass are equivalent, so strictly speaking mass must also be considered as being converted into energy; in other words, the theory of relativity can be seen as unifying the law of conservation of energy and the law of conservation of mass.

外界から遮断されて閉じた系においてはその中のエネルギーの総和は一定となる. 熱力学の第一法則*の形を変えたものとみることもできる.この形のエネルギー保存法則は,マイヤー,ヘルムホルツ,ジュールの三人の研究の結果確立されたものである.相対性理論によればエネルギーと質量とは同等であるから,厳密には質量もすべてエネルギーに換算したもので考えなくてはならないが,換言すれば,相対論によってエネルギー保存法則と質量保存の法則が統一されたとみることもできる. 出典 朝倉書店法則の辞典について 情報 |
