静电力是电磁学的基本概念,而对静电力的功的分析与计算则是理论力学的一个重要內容,这个问题表面看来只不过是将具体的物理问题转化为数学问题,然而,由于计算中涉及较多的数学方法,学生不易掌握,而且在应用过程中还涉及是否“可行”,是否“最优”的问题。通过多年的教学和实践,下面就这一问题作进一步的分析与探讨。 Electrostatic force is the basic concept of electromagnetism, but the analysis and calculation of the work of electrostatic force is an important content of theoretical mechanics. On the face of this problem, it is only the transformation of specific physical problems into mathematical problems. However, due to the calculation There are a lot of mathematics methods involved, which are not easy for the students to grasp, and it also involves whether or not it is “feasible” and whether it is “optimal” in the application process. Through years of teaching and practice, the following analysis and discussion will be made on this issue.
