物理图象能形象地表达物理规律、直观地描述物理过程、清晰地反映物理量间的函数关系。用图象法解题不但快速、准确,而且可以避免繁杂的中间运算过程,甚至还可以解决用解析法无法解决的问题。比如速度-时间图象、位移-时间图象等等。通常在应用图象法解决物理问题时会关注物 Physical images can vividly express the laws of physics, visually describe the physical processes and clearly reflect the functional relationships between physical quantities. Using image method to solve problems is not only fast and accurate, but also can avoid complicated intermediate calculation process, and even solve the problem that can not be solved by analytical method. Such as speed - time images, displacement - time images and so on. Objects are often used when solving physical problems using image methods
