数学作为研究物理问题的工具,在初中物理中的任务,主要包括两个方面:一是从物理现象与过程的分析中,经过概括、抽象等手段,把物理问题转化为数学问题;二是综合运用初等数学知识,正确、迅速地进行有关物理问题的运算.然而,不少同学在“转化”与“运用”的过程中,不是转化不能显示出解题的思路,就是运算出错或找不到简捷方法,费力费时,本文以方程(组)为例,来探讨其在解决物理问题中的“转
Mathematics as a tool for the study of physical problems, the tasks in junior high school physics, mainly includes two aspects: First, from the analysis of physical phenomena and processes, through generalization, abstraction, and other means, the physical issues into mathematical problems; The use of elementary mathematics knowledge, the correct and rapid calculation of the physical problems. However, many students in the process of ”transform“ and ”use ", is not converted can not show the idea of solving the problem, that is, the operation error Or you can’t find a simple method that is laborious and time-consuming. This article uses equations (groups) as an example to discuss its turn in solving physical problems.
