传送带问题一直是高中物理课程比较容易出现,且难度系数较大的题型,以其运动过程繁琐、涉及概念的多而著称.尤其是倾斜传送带,如何运动,运动阶段如何区分,能否最终匀速一起运动等等以及其涉及到的多个概念(如痕迹、电能、内能、摩擦力所做的功等)有什么联系、什么区别,如何计算等等问题交织,最终学生谈之色变.作为这样难而涉及知识点全的内容,高中物理课上却甚少将它作为一个专题,除了长期以来的教学
Conveyor belt problem has always been more likely to appear in high school physics courses, and the difficulty of a large number of questions, with its complicated process, involving more than the concept known, especially inclined conveyor belt, how the movement, how to distinguish between stages of movement, whether the final uniform speed Movement and so on and its related concepts (such as traces, electricity, internal energy, friction work done) what is the connection, what is the difference, how to calculate and so on intertwined, and ultimately the students talk about the color change. As difficult as it relates to the content of the whole point of knowledge, high school physics class seldom regarded it as a topic, in addition to long-term teaching
