上高中后,不少同学反映物理学习起来很难,听老师讲好像懂了, 但在真正做题时又不好入手.要解决这个问题,要学好物理,首先要掌握好课本,尤其是在高一、高二阶段,更要把基础夯实,对课本定义要理解准确和辨析清楚.比如什么是速度,什么是质量……对这些问题有一点模糊都不行,考试中解选择题时有模糊的地方就得靠定义解决,很简单的如速度相同或相等之 After attending high school, many students reported that it was difficult to learn physics. Listening to the teacher seemed to understand it, but when doing the actual question, it was difficult to start. To solve this problem, to learn physics, we must first master the textbook, especially In the first and second grades of high school and senior high school, it is necessary to reinforce the basics and understand the definition of textbooks accurately and clearly. For example, what is the speed and what is the quality... It is not possible to blur these questions. The place has to be solved by definition. It is very simple if the speed is the same or equal.
