在高中物理习题中,传送带问题是常见的一类动力学问题,该问题涉及知识点多,物理过程复杂,考查范围广,是许多学生比较头疼的问题。为了让学生能够突破此类难题,抓住解题关键,明确解题思路,现将该问题作一剖析。一、在传送带问题中,物体的动力学分析是要突破的首个难题为了详细了解物体在传送带上的运动情况,现对传送带的两种基本模型进行剖析。物体运动情况均以地面为参考系,传送带匀速且足够长的情况下:1.水平传送带模型 Among high school physics exercises, the conveyor belt problem is a common type of kinematic problem. This problem involves many knowledge points, complex physical processes, and a wide range of examinations. It is a problem many students find troublesome. In order to enable students to break through this type of problem, grasp the key to solving problems, a clear idea of ​​solving problems, now the problem for an analysis. First, the conveyor belt problem, the dynamic analysis of the object is to break the first puzzle In order to understand the object in detail on the conveyor belt movement, the conveyor belt is now analyzed two basic models. Object movement are ground reference frame, the conveyor belt uniform and long enough: 1. Horizontal conveyor model
