能量守恒定律

能量守恒定律（英语：law of conservation of energy）阐明，孤立系统个总能量 E 保持弗变。如果一个系统处于孤立环境，即弗能有任何能量或质量从该系统输入或输出。能量弗能无故生成，也弗能无故摧毁，但渠能够改变形式，例如，拉炸弹爆炸个过程中，化学能可以转化为动能William John Macquorn Rankine (1853) "On the General Law of the Transformation of Energy," Proceedings of the Philosophical Society of Glasgow, vol. 3, no. 5, pages 276-280; reprinted in: (1) Philosophical Magazine, series 4, vol. 5, no. 30, pages 106-117 (February 1853); and (2) W. J. Millar, ed., Miscellaneous Scientific Papers: by W. J. Macquorn Rankine, ... (London, England: Charles Griffin and Co., 1881), part II, pages 203-208: "The law of the Conservation of Energy is already known—viz. that the sum of all the energies of the universe, actual and potential, is unchangeable."。
