在数学上 ,从小学到初中都要学习“正比例”和“反比例”的有关知识 ,懂得了正比例和反比例用来解决有关物理问题时 ,不能机械套用 ,要根据物理公式和每个物理量的具体含义来解答、解释有关的物理问题 ,否则就会误入歧途或不能真正学好物理知识。下面对初中物理公式中容易用数学上的“正比例”和“反比例”来错误理解的几个问题进行分析
In mathematics, from primary school to junior high school, we must study the knowledge of “proportionality” and “inverse proportion,” and understand that when proportional and inverse proportions are used to solve physical problems, they cannot be applied mechanically, but must be based on physical formulae and the specific meaning of each physical quantity. To answer and explain the relevant physics problems, you will go astray or fail to learn physical knowledge. The following is an analysis of several problems that are easily misunderstood by the mathematics “proportional” and “inverse proportion” in the junior physical formula.
