《物理教学》1991年第4期第40页刊登的《速摩关系上的一个错误》(下称《速文》)指出并纠正了《物理教学》1990年第9期第25页刊登的《培养学生的形象思维、重视物理过程分析》中(下称《培文》)出现的速度关系上的错误。但是,却没有发现,当然也没能纠正《培文》上出现的加速度关系上的错误。因而《速文》给出的答案并不正确,本文的目的就是要指出和纠正两文中加速度关系上的错误并给出该问题的正确解答。为了方便,将题目全文和《速文》给出的解答摘要,抄录如下。题目如图1所示,砝码 A、B 和小球 C 的质量都
The book “A Mistake in the Relationship between Speed and Fury” (hereinafter referred to as “Astronomy”) published in “Physics Education,” No. 4, 1991, p. 40 points out and corrects the publication of “Physics Education,” Issue 9, 1990, p. 25. The errors in the relationship between speeding up the emergence of students’ image thinking and valuing physical process analysis (hereinafter referred to as “Pei Wen”). However, it has not been discovered, of course, failed to correct the errors in the relationship between the acceleration of “Pei Wen.” Therefore, the answer given in the “Action” is not correct. The purpose of this paper is to point out and correct the errors in the acceleration relationship between the two texts and give a correct solution to the problem. For the sake of convenience, the full text of the title and the summary of answers given in the “Action” are reproduced below. The title is shown in Figure 1, and the masses of the weights A, B and ball C are
