机械能守恒定律及动量守恒定律演示仪器的制作

Making of Demonstration Instrument of the Law of Conservation of Mechanical Energy and Momentum Conservation Law

制作一种可以同时验证机械能守恒和动量守恒的实验装置,并通过这两个实验现象的对比更显著地体现了两个实验的物理现象与原理,有利于学生对机械能守恒与动量守恒原理的理解与认知。

A kind of experiment device which can also verify the mechanical for conservation and momentum conservation was made. Through the comparison of the two experimental phenomenon more significantly reflects the physical phenomenon and theory of two experiments, which is helpful for students to understand and cognition of mechanical energy conservation and momentum conservation principle.
