摘要
为了辅助摩擦力的教学,自制了摩擦力演示装置,通过模拟电路与数字电路的转换可以直接显示出滑块与传送带间的摩擦力.该装置不仅可以探究静摩擦力和滑动摩擦力,而且还可直观地显示出物体间摩擦力的渐变过程.
In order to improve the teaching effect of friction force,a demonstration device was designed.This device could directly show the friction force between slider and conveyer-belt using analog and digital circuits.The device could show static friction and sliding friction.
