摘要
通过2007年的一道高考题对高中实验"验证动量守恒定律"中的落点顺序问题进行了详细的分析.结果表明,小球落点的位置顺序不仅与小球的质量有关,还与碰撞的种类有关,并给出了实际实验时落点顺序唯一性的原因.
The order of the point of fall in the experiment of validating momentum conservation in high school is analyzed in detail. The result shows that the point of fall is related with the ball quality and the kind of collision. And the reason that the order of the point of fall is practically determinate is presented.
