公式法和图象法是解决物理问题的两种基本方法,各有优缺点。在对实验结果进行误差分析时,图象法简洁直观、巧妙快捷,公式法逻辑严密,容易理解。对于适合用图象法求解的问题,学生也应该知道如何用公式法求解,以期通过对比,体会两种方法的优缺点,更深刻地理解所研究的物理问题。 The formula method and the image method are two basic methods to solve the physical problem, each has its advantages and disadvantages. In the error analysis of the experimental results, the image method is simple and intuitive, clever and efficient, the formula method is logical and easy to understand. Students should also know how to use formula method to solve the problem that is suitable for solving with image method, in order to understand the advantages and disadvantages of the two methods and understand the physical problems under study comparatively.
