传送带问题是以真实物理现象为依据的问题,它既能训练学生的科学思维,又能联系科学、生产和生活实际,因而,这种类型问题极具生命力。本文从牛顿运动定律的角度对传送带问题作了详尽的阐述,将传送带分为了三种类型分别具体举例,借以总结问题的突破方法,并作了变式拓展,以深化体会。
The problem of conveyor belts is based on real physical phenomena. It can train students’ scientific thinking but also connect science, production, and life. Therefore, this type of problem is extremely vital. This article elaborates the problem of conveyor belts from the perspective of Newton’s motion law, divides the conveyor belt into three types and gives specific examples, in order to summarize the breakthrough methods of the problem, and has made variable extensions to deepen the experience.
