高一物理实验“验证动量守恒定律”和“验证机械能守恒定律”是两个极为重要的分组实验 .从恢复高考到现在 ,有关这两个实验的试题出现频数较多 ,各种复习资料中有关这两个实验的复习题也较多 .同样 ,有关这两个实验的误解也不少 ,笔者认为 ,有必要就这些问题进行一下探讨 .一 The first-year physics experiment “Verification of Conservation of Momentum” and “Verification of the conservation of mechanical energy” are two extremely important grouping experiments. From the resumption of the college entrance examination to the present, the frequency of test questions related to these two experiments is more and more relevant in various review materials. There are also more review questions for these two experiments. Similarly, there are also many misunderstandings about the two experiments. The author believes that it is necessary to discuss these issues.
