力学知识是学习物理的基础,贯穿高中物理的每一个章节,是历年高考中进行综合能力考查的一块“热土”,分数比例大,题目难度高.许多问题因涉及物体多、过程复杂而困扰学生,甚至用解析法难以顺利解答,此时如果科学地运用图像分析,会茅塞顿开,可谓强攻不如智取.下面例举3题,以飨读 The knowledge of mechanics is the basis for learning physics. It runs through every chapter of high school physics and is a “hot spot” for comprehensive ability examinations in previous college entrance examinations. It has a large proportion of scores and a high degree of difficulty. Many problems plagued students due to the large number of objects involved and the complexity of the process. , Even with the analytical method is difficult to answer smoothly, at this time if the scientific use of image analysis will be dull and open, it can be said that storming is better than taking. Here are three examples to read
