“拉击”问题的研究
发布时间:2018-08-09 15:01
【摘要】:目前,一些教师及学者对“拉击”过程的认识存在问题,误把“拉击”和碰撞这两种不同的物理过程当成一回事,以及对“拉击”具体性质的看法不统一,在解答与“拉击”有关的例题时也存在各种各样的错误。本文会将“拉击”问题的性质进行研究,并将“拉击”问题与碰撞问题二者之间的异同进行对比,归纳总结出“拉击”类问题的解题依据和解题规范。同时,对轻绳“拉击”和链条的“拉击”两种情况中具有代表性的例题进行研究。最后对中学物理教材相关知识的编写和教师对绳模型的教学提出一些建议。
[Abstract]:At present, some teachers and scholars have some problems in their understanding of the process of "pull and strike", mistaking the two different physical processes of "pull and strike" and collision as the same thing, as well as different views on the specific nature of "pull and strike". There are also various errors in solving examples related to "pull-click". In this paper, the nature of the "pull and strike" problem is studied, and the similarities and differences between the "pull strike" problem and the collision problem are compared, and the basis for solving the problem and the standard for solving the problem are summed up. At the same time, the typical examples of light rope "pull" and chain "pull" are studied. Finally, some suggestions are put forward on how to compile the relevant knowledge of physics teaching materials in middle schools and how to teach the rope model by teachers.
