摘要
以普通物理的三个典型的力学习题为例,展示了适合于普通物理教学但不同于理论力学的拉格朗日方程的能量解析方法。
This present article takes three typical mechanical exercises of General Physics as example,demonstrating the suitable method for the teaching of general physics,which is different from the energy analysis method of Lagrange equations in theoretical mechanics.
