我们可以用文字来描述物理规律,还可以用图象来描述.利用图象解决物理问题描述物理规律的方法称之为图象法.物理图象有很多类型,如模型图、受力分析图、过程分析图、矢量合成分解图、函数图象等.图像法能够根据题意把复杂的物理过程简洁的表示成物理图像,将物理量间的代数关系转变为几何关系,运用图像直观、形像、简明的特点,来分析解决物理问题,由此达到化难为易、化繁为简的目的.所以图像法可以提高 We can use the text to describe the laws of physics, but also can be used to describe the image. The use of images to solve physical problems described physical laws called image method. There are many types of physical images, such as model diagrams, stress analysis , Process analysis chart, vector synthesis decomposition chart, function image, etc. The image method can express the complicated physical process into the physical image succinctly according to the title, change the algebraic relation between the physical quantities into the geometric relation, use the image visualization, the image , Concise features, to analyze and solve the physical problems, so as to achieve the purpose of making things difficult and simplifying, so the image method can be improved
