在物理习题中,遇到的运算非常多,它要借助于数学工具,解题过程中,要考虑其物理意义,使用什么数学方法完全取决于物理过程本身.但是某些物理问题,却被某些数学知识所阻碍,形成了习题教学的误区,因此进行专门的数学技巧和数学障碍的分析就显得十分必要.本文就这方面问题摘取几个片段浅析如下.一、物理意义与数学意义无法沟通造成的误区例1在xoy平面内,有很多质量为m,电量为e
In physics exercises, there are a lot of computational problems encountered, and it depends on mathematical tools. In solving the problem, we must consider its physical meaning and what mathematical method to use depends entirely on the physical process itself. However, some physical problems are solved by some Therefore, it is very necessary to carry on the analysis of special maths and maths obstacles.This article is based on the analysis of several sections of the questions in this area.First, the physical meaning and the mathematical meaning Misunderstandings caused by inability to communicate Example 1 In the xoy plane, there are many masses of m and e
