液体反冲实验是高中物理《动量守恒定律》一章的一个重要演示实验,它是动量守恒知识的一个重要应用。该演示实验若是按照教材(普通高中课程标准实验教科书《物理》选修3-5)第23页图16.5-4所示器材去完成,实验过程中还存在一些不足。本人根据几年的实际教学实践,对该演示实验进行了改进设计,改进后设计制作的实验演示器能控制旋转体内
Liquid recoil experiment is an important demonstration experiment in the chapter of “law of conservation of momentum” in high school physics. It is an important application of knowledge of momentum conservation. If the demonstration experiment is completed according to the equipment shown in Figure 16.5-4 on page 23 of the textbook (Physics course of elective 3-5), there are still some shortcomings in the experiment. According to several years of actual teaching practice, I improved the design of the demonstration experiment, improved experimental design demonstrator can control the rotation of the body
