在高中物理的静力学、运动学、动力学和电磁学的习题中,都有一些取值范围问题。所谓取值范围,就是所求的物理量在一定的范围之内,常见的有如下两种类型:(1)隐性取值范围问题;(2)显性取值范围问题。所谓隐性就是题目的条件隐蔽,要靠自己分析判断,使之显山露水;所谓显性就是题目所求开宗明义,只要使所求量在两个量之间即可。本文仅对一些常见的取值范围问题作粗浅的例析,仅供大家参考。
In high school physics statics, kinematics, dynamics and electromagnetism exercises, there are some problems with the range of values. The so-called range of values is that the required physical quantity is within a certain range. Commonly there are the following two types: (1) the range of implicit values; (2) the range of explicit values. The so-called “hidden” is the concealment of the subject’s conditions, and it is necessary to rely on one’s own analysis and judgment to make it appear dewy. The so-called explicitness is the subject’s seeking openness and righteousness, so long as the quantity sought is between two quantities. This article only makes some superficial analysis of some common range of values, for your reference only.
