摘要
本文讨论关于简谐振动能量的普遍形式。论证由弹簧振子得到的谐振动势能为1/2KX^2,总能量为1/2KA^2,对任一作简谐振动的系统,只要势能零点取在平衡位置,都是成立的。
This paper discusses general forms of the energy of simple harmonic oscillations.We prove that the potential energy is(1/2)Kx^2 and total energy is(1/2)KA^2. And they are always frue provided that the zero point of the potential is chosen at the equilibrium position.
