自由落体运动是运动学章节中经常被选做公开课的热门内容。该节既涉及物理学史,又有实验操作,还有相关规律的探究和应用。目前各版本高中物理教材对该节内容的阐述虽然大同小异,但衍生出的优秀教案、教学视频却各有千秋。鉴于众多相关资源的堆积,笔者无意重复。因此,本文只是对该节内容的引入提出自己的一点想法。对于落体问题,多数时候,我们的教材或教学设计都是从批判亚里士多德的“重快轻慢”人手的。然后根据伽利略的相关推理,以及“牛顿管”实验来说明在没有空气阻力的情况下,物体落地其实应该是“一样快”。这里有个问题,就是为什么要忽略空气阻力?回答好这个问题,自由落体运动的引入也就顺理成 Free-fall is a popular part of the kinematics chapter often chosen as an open class. This section involves both the history of physics, but also experimental operation, as well as the exploration and application of relevant laws. Although the present version of high school physics textbooks on the content of the section described much the same, but derived from the outstanding lesson plans, teaching videos are different. In view of the accumulation of many related resources, I do not intend to repeat. Therefore, this article is just a little idea of ​​the introduction of this section. For the fall problem, most of the time, our teaching materials or instructional design criticize Aristotle’s “fast and slow” manpower. Then based on Galileo’s reasoning, and the Newtonian experiment, the object should actually be “as fast as possible” without air resistance. Here’s a question, why do you want to ignore the air resistance? Answer this question well, the introduction of free fall movement will be logical
