图象是表示物理规律的方法之一,它可以直观地反映某一物理量随另一物理量变化的数值关系,形象地描述物理规律。应用图象法解答物理题,可避免一些较为复杂的推导运算,从而简化解题程序,给解题带来诸多方便。现以近年全国高考题为例解析如下。 Image is one of the methods of representing physical laws. It can intuitively reflect the numerical relationship between the change of a physical quantity with another physical quantity and vividly describe the physical laws. Using image method to solve physical problems can avoid some of the more complex derivation operations, thus simplifying the problem-solving process and bring many conveniences to the problem solving. The examination of the national college entrance examination questions in recent years is as follows.
