大学物理若干问题教学探讨

Discussion about Some Problems in College Physics Teaching

现行大学物理教材存在一些不足,一是角动量定理的表述方式和动量定理、动能定理的表述方式不一致;二是三大运动定理的引入不尽科学;三是确定简谐运动初相的方法不完善;四是对接地导体的带电问题的处理跳跃性太大。文章逐一分析了这些不足,并提出了改进建议。

There are some defects in college physics books, and the main defects are as the following. The first is that the state fashion of the theorem of angular momentum is not the same as the state fashion of the theorem of momentum and the theorem of ki- netic energy. The second is that the introduction of the 3 theorems of motion is not scientific. The third is that the method of calcula- tion of the initial phase of the simple harmonic motion has some small problems. And the fourth is that the content about the problem of the electrification of the conductors which are connected with the earth is too simple. The defects are analyzed one by one, and the suggestions of improvement are advanced.
