近来关于“探究加速度与力、质量的关系”装置改进的文章很多,笔者也曾撰文讨论了该装置的改进,刊于《物理教学探讨》2010年10期(为叙述方便,以下简称原文)。针对有些读者的来函商议,以及各种刊物对这个问题的讨论,笔者再来谈一些看法。一、“改进”并不是对课本装置的否定教材装置如图1所示,存在的主要问题是小车 Recently on “to explore the relationship between acceleration and force, quality,” a lot of device improvement articles, I also wrote an article on the improvement of the device, published in “Physics Teaching” 2010 the 10 period (for the convenience of narration, hereinafter referred to as the original ). In response to the letters and calls of some readers, as well as various publications on this issue, let me talk about some ideas. First, “improvement ” is not a negation of the textbook device teaching device shown in Figure 1, the main problem is the car
