能否正确的选取研究对象,是解决高中物理问题的关键。也是我们在教学中经常强调的问题。而对象又可分为选整体(可能是全部中的几个)为对象和选隔离开的单个物体为对象。我今天就针对整体与隔离法在经常见到的斜面问题中做一定的总结和归纳。 The correct choice of the research object is the key to solve the physics problem in senior high school. It is also what we often emphasize in teaching. The object can be divided into the whole body of the election (which may be all of several) for the object and the election isolated from a single object as an object. Today, I will summarize and summarize some of the beveled problems that I have seen so often on the whole and the isolation law.
