图象法是在对物理现象或过程分析的基础上 ,运用相关的物理规律 ,确定变量之间的函数关系 ,作函数图象 ,再根据图象的物理意义讨论和解决问题的方法。由于用图象法来表示物理规律往往比公式法形象、直观 ,所以用图象法求解物理题 ,有时能达到简解、巧解物理题的目的。运动图象 The image method is based on the analysis of physical phenomena or processes, the use of relevant physical laws to determine the functional relationship between variables, function images, and then discuss and solve the problem based on the physical meaning of the image. Because the use of image method to represent the physical laws is often more intuitive than the formula method, the use of image methods to solve physical problems, sometimes to achieve a simple solution, the purpose of solving the physical problem.
