目前对碰撞过程内力作功的研究在国内编著和翻译出版的《普通物理学》和《理论力学》的教材中 涉及的很少。而在闫金铎、李椿、王殖东编的《普通物理学讲义》第一册第一版一百五十页上虽提出了碰撞过程内力作功的概念,但没有详细解释,要使学生确实理解内力作功的概念,辅导教师需作进一步的研究和分析。为此我们建立了以下碰撞过程的模型,并详加 At present, the researches on the internal forces in the collision process involve little in the teaching materials of “general physics” and “theoretical mechanics” compiled and translated in China. However, although the concept of internal force in collision process was proposed in the first page of the first edition of the first volume of “General Physics Handout” written by Yan Jinduo, Li Chun and Wang Shidong, it has not been explained in detail, Understand the concept of internal strength work, counseling teachers need further research and analysis. To this end we have established the following model of the collision process and detailed
