摘要
对"圆锥摆粗略验证向心力表达式"实验进行改进,采用减速电动机通过轻杆带动大钢球做匀速圆周运动,形成圆锥摆.改进后的装置运行稳定,操作简单.
The experiment of roughly validating the expression of the centripetal force was im- proved. Driven by motor and light pole, the big steel ball did circular motion as a conic pendulum. The improved device was stable and simple.
