物理图像能形象地表达物理规律、直观地展示物理图景、清晰地反映物理量间的函数关系,还常能表示其他物理量的变化情况.而充分利用图像的功能来达到理解、解读题设条件中的物理情景,寻找物理量之间关系的方法,更是被广泛应用.可以说,图像法已经成为物理学中常用思维方法之一,在力学竞赛中有不少问题中的奇思妙想也 Physical images can vividly express the physical laws, display the physical images visually, clearly reflect the functional relationships among the physical quantities, and often represent the changes of other physical quantities. However, taking full advantage of the image functions to understand and interpret the conditions Physical scenarios, the way to find the relationship between physical quantities, but also is widely used.It can be said that the image method has become one of the common thinking methods in physics, mechanics competition, there are many problems in the whimsy
