对“作用力与反作用力的关系”实验的创新

Improving the experiment on "the relation between force and reaction force"

人教版教材在设计"作用力与反作用力的关系"实验时,忽视了用不同性质的力来定量验证牛顿第三定律,使得验证实验有失普适性.为此设计了通过发生相互作用的滑动摩擦力来定量验证牛顿第三定律的实验方案,并给出了实验的方法、技巧和结果.

The experiment of ＂the relation between force and reaction force＂ introduced in the textbook which published by Peoples Education Press could not quantitatively validate Newton third law with different kind of forces. So a new experimental program is designed, which can quantitatively validate Newton third law by sliding friction force. The experimental methods, techniques and results are introduced.
