论文部分内容阅读
应用动量和能量的观点求解的问题,是力学三条主线中的两条主线的结合,是中学物理中涉及面最广,灵活性最大,综合性最强,内容最丰富的部分.而“碰撞问题”的处理是高中物理中比较重要的一部分内容,但我发现教学中有时候学生对于此类问题很难把握.特别是一些类似的题目不懂得运用这个模型,而一旦那些没有做过见过的题目就会犯难,不知道如何下手.本人就对此类问题的解决方法做了总结.为此先来看一下碰撞的知识.
The problem of applying momentum and energy to solve the problem is the combination of the two main lines in the three main lines of mechanics and is the most extensive, flexible, comprehensive and content-rich part of secondary physics, and the collision of Problem "is a relatively important part of high school physics, but I found that sometimes students in teaching difficult to grasp such issues, especially some of the similar topics do not know how to use this model, and once those who have not done before Over the subject will be guilty of trouble, I do not know how to start. I made a summary of the solution to such problems .To this first look at the collision of knowledge.
