人教版高中课程标准实验教科书·物理(选修3-5),在“反冲运动、火箭”[1]一节中,介绍了演示反冲旋转现象的实验装置:如图1所示,把弯管装在可旋转的盛水容器的下部.当水从弯管流出时,容器就旋转起来.我们用矿泉水瓶代替锥形容器制作的装置,实验效果非常明显.1制作器材高约22cm的矿泉水瓶1个,中性笔笔芯(或牛奶吸管)1根,细线1根,清水、胶带纸等.2装置制作 PEP (High PEP) High School Curriculum Standard Experimental Textbook / Physics (elective 3-5). An experimental setup for demonstrating recoil spin phenomena is presented in the section entitled “ROCK REAL, rocket” [1] , The elbows installed in the lower part of the rotatable water container when the water flows out from the elbow, the container is rotated.We use mineral water bottles instead of conical containers made of the device, the experimental effect is very clear .1 high production equipment 22cm mineral water bottle 1, gel pen (or milk straw) 1, a thin wire, water, tape, etc. 2 device production
