摘要
应用牛顿第二定律分析了自由落体的冲击问题,不仅可以得到与能量法相同的结果,同时还能求出在冲击过程中冲击物的加速度的变化规律和冲击所持续的时间,并对用能量法导出的计算公式进行了修正和完善。
Based on the Newton's Second Law, the impact problem of a free falling object is analyzed in this article. The obtained result is the same as that by the Energy Method. Furthermore, the variation of acceleration during the impact process and the impact time can be derived. The related formula derived from the Energy method are modified and improved.
