高中物理解题,实际上是对物理现象的分析和描述,而描述物理现象的数学工具就是用物理公式建立相关的方程,这样的方程,我们称之为“物理方程”.一个比较复杂的物理问题,往往需要建立好几个方程才能奏效.不少学生在拿到一个物理问题时,其着眼点往往不是去分析物理现象,不是去考虑如何用所学的物理原理去分析物理状态与过程,而是把注意力放在所要求解的结果上去了.其实,当把物理现象用物理公式正确地列出方程之后,其结果自然会水到渠成.本文对此做一探讨.
The high school physical understanding problem is actually the analysis and description of physical phenomena, and the mathematical tool for describing physical phenomena is the use of physical formulas to establish the relevant equations. Such equations are called “physical equations”. A relatively complicated one. Physical problems often require the establishment of several equations to be effective. When many students get a physical problem, their focus is not to analyze physical phenomena, not to consider how to use physical principles to analyze physical states and processes. Instead, attention is paid to the results of the required solutions. In fact, when the physical phenomena are correctly listed in the physical equations, the results will naturally come to fruition. This article discusses this.
