摘要
通过分析不同情况下弹簧振子的运动规律、能量的转化过程,得出了弹簧振子在振动过程中能量转化和守恒定律的通用表达形式.若选择弹簧振子的平衡位置为坐标原点,无论弹簧振子处于何种均匀的保守力场中,其机械能守恒定律的最终表达式将完全相同.
By analyzing the process of the motion and the energy transformation of the spring oscillator moving in different case, the simple and current expression of mechanical energy conservation law has been gotten. If we choose the coordinate origin at the balance position of the spring oscillator, in any uniform conservation field of force, the formulation of mechanical energy conservation law of the spring oscillator will be the same form.
