1 物理量非单调变化的分析判断在高中物理中,物理量的定义式和定理、定律的表达式有许多不同的形式,我们称之为公式。在解决一个具体的物理问题的时候,要运用多个物理公式,当这些物理公式,依据解决问题的实际需要,交叉套叠在一起,则物理量间的制约关系变得错综复杂。它们的量的关系形式可分为周期性变化和非周期性变化,而非周期性变化又分为单调变化和非单调变化。其中物理量间的非单调变化关系往往不为一般学生所熟悉和重视,学生习惯于一般性
1 Analysis of non-monotonic changes in physical quantity In high school physics, there are many different forms of the definition of the physical quantity and the expression of the theorem and the law, which we call the formula. When solving a specific physical problem, a number of physical formulae must be used. When these physical formulas are interspersed with each other according to the actual needs of solving the problem, the constraints between physical quantities become intricate. The relationship between their quantities can be divided into periodic and non-periodic changes, while non-periodic changes are divided into monotonous and non-monotonic changes. The non-monotonic relationship between physical quantities is often not familiar and important to the average student, students are accustomed to the general
