“锥体上滚”实验演示了一个看似违反规律的现象:一个双锥体仅在重力场的作用下(忽略空气阻力)从斜面低端自动滚动到斜面顶端。这种“反常”现象能引发学生学习和探究的好奇心,现将该实验的实验装置及其原理阐述如下。一、实验装置锥体上滚的实验装置主要是由演示仪底座、2根不平行放置的横杆、双锥体等组成。双锥体是关于中间对称的两个椎体,且中间厚,两端薄。实验 “Cone roll ” The experiment demonstrated a seemingly violating the law: a double cone only under the action of the gravitational field (ignoring the air resistance) automatically rolls from the lower end of the bevel to the top of the bevel. This “abnormal ” phenomenon can lead to curiosity of students to learn and explore, now the experimental device and its principles are described below. First, the experimental device Cone roll on the experimental device is mainly composed of the demo base, two parallel bars placed in parallel, double cone and so on. Double cone is about the middle of the two symmetrical vertebra, and the middle of the thick, thin at both ends. experiment
