如果遇到的物理问题由于研究对象或已知条件不够明确,通常采用分类思想,对研究对象或已知条件进行合理分类,然后根据物理规律运用列表法对分类项进行逐一分析求解,最后再综合归纳,有效解决问题。分类,不仅是一种逻辑方法,也是一种策略思想。
If the physical problems encountered because the research object or known conditions are not clear enough, usually using the classification idea, the object of study or known conditions for a reasonable classification, and then use the list method according to the laws of physics to analyze the classification items one by one, and finally integrated Induce, solve problem effectively. Classification, is not only a logical method, but also a strategic thinking.
