图象是数与形相结合的产物,是具体与抽象相结合的体现.用图象法解决物理问题常常能弥补纯数学运算的不足,使问题的结论变得更加直观明了.例如,由匀变速直线运动的v—t图象,我们不仅可以了解物体运动速度的变化情况,还可方便地求得物体的位移、路程等物 Image is a combination of number and shape, which is the embodiment of the combination of abstraction and abstraction.Improving the physical problems by image method can often make up for the deficiency of pure mathematical operation, and make the conclusion of the problem become more intuitive.For example, Linear motion of the v-t image, we can not only understand the changes in object velocity, but also can easily calculate the object’s displacement, distance and other things
