等效质量概念及其在解题中的应用浙江省玉环县教委教研室郑青岳一、等效质量概念的引出如图１所示，物体Ａ和Ｂ仅受到两者的相互作用力Ｆ，它们对地的加速度分别为ａ１和ａ２．若Ａ相对于Ｂ的加速度为ａ＇，根据牛顿第二定律．有将①、②两式变换成上述推导及其结果表明，... The Concept of Equivalent Quality and Its Application in Solving Problems Zheng Qingyue, Teaching and Research Office, Yuhuan County, Zhejiang Province. The concept of the equivalent quality concept is shown in Fig. 1. Objects A and B are only subjected to the interaction force F of the two, and they are opposite to the ground. The accelerations are a1 and a2, respectively. If A’s acceleration with respect to B is a’, according to Newton’s second law. There are 1,2 and 2 transformations into the above derivation and the results show that...
