常说学习物理难,物理难学的原因是什么呢?笔者认为是学生的解题出现了障碍和困惑,说到底是思维方法出现了困难,本文选择力学问题这一视角,就解决力学问题的几种思维方法进行探讨,望能有助于课堂实践。一、图像思维法1.方法概述图像法:一是利用图像本身的数学特征所反映的物理意义解决物理问题;二是为明确物理量之间的函数关系,做出物理图像解决问题,通常我们遇到的图
I often say that learning physics is difficult, what are the reasons why physics is hard to learn? I think that there are obstacles and puzzles in the students’ problem solving. In the final analysis, there are some difficulties in thinking methods. In this paper, we select mechanics problems and solve the problems of mechanics Several ways of thinking to explore, hope can help classroom practice. First, the image thinking method 1. Method Overview Image method: First, the use of the image itself reflects the physical characteristics of the physical meaning of the physical problems; the second is to clear the physical relationship between the physical function to make a physical image to solve the problem, usually we encounter To the map
