在物理总复习中，常会遇到一些综合性较强的计算题．正确分析并解答综合题对提高同学们的综合分析能力是大有好处的．初中物理的综合题类型较多，其中有一类常见的综合题——能量转化问题．不少同学在练习时思路不清，概念模糊，产生错误判断，下面就这个问题进行归纳分析并分 In the physical review, we often encounter some comprehensive calculation problems. Correctly analyzing and answering comprehensive questions is a great benefit to improving students’ comprehensive analytical skills. There are many types of comprehensive problems in junior high school physics, and there is one common type of problem-energy conversion. Many students have unclear thinking in the practice, the concept is ambiguous, and they produce erroneous judgments. The following questions are summarized and analyzed.
