“力的合成”法则在初中和高中物理教学中虽然在内容和理解层次上有所不同,但都是这两个阶段涉及的力学知识中的重点和难点问题。多年的教学经验证明,通过实验为学生提供尽可能精确的事实性实验依据是帮助学生正确理解这一问题的最关键所在。为此,笔者设计了一套制作简单,易操作,且实验现象明显的“力的合成演示器”装置,现介绍如下,供大家参考。 Although the “combination of force” principle differs in the level of content and understanding in physics teaching in junior high school and high school, it is a key and difficult problem in the knowledge of mechanics involved in these two stages. Many years of teaching experience have proved that providing students with the most accurate factual experimental evidence through experiments is the key to helping students understand this issue correctly. To this end, the author designed a set of “composite demonstrator for force” devices that are simple to produce, easy to operate, and have obvious experimental phenomena, and are presented below for your reference.
