传送带问题是中学物理中的一个常见模型的问题,在解答传送带问题时,由于物体与传送带均在运动,运用的知识点较多(力的分析、运动的分析、牛顿运动定律等),解题过程也较复杂,所以这类问题往往是习题教学的难点,也是高考考查的一个热点.对此,下面通过一道水平传送带习题及其变式题为例,阐述处理这类问题的方法,以作抛砖引玉. The problem of conveyor belt is a common problem in middle school physics. When solving the problem of conveyor belt, the problem of using knowledge is more due to the movement of the object and the conveyor belt (force analysis, motion analysis, Newton’s law of motion, etc.) The process is also more complicated, so these types of problems are often difficult teaching exercises, but also a hot spot for college entrance examination.To this, through a horizontal conveyor exercises and variants of the problem as an example, to deal with this type of problem, Initiate
