利用图象来表示物理量的变化规律,是学习物理的数学手段之一,它既能形象、直观地表示一个物理量随另一个物理量变化的情况,把抽象复杂的物理规律有选择地、具体地表现出来,帮助我们加深对一些物理概念和规律的理解;又能将一些抽象的数学公式
The use of images to represent the variation of physical quantities is one of the mathematical means of learning physics. It not only shows the changes of one physical quantity with the other physical quantity vividly and intuitively, but also presents the abstract and complex physical laws selectively and concretely Come out and help us to deepen our understanding of some of the concepts and laws of physics; we can abstract some mathematical formulas
