根据传送带运送物体的实际情形,在高中物理、自主招生、竞赛辅导中,设计出很多考察物理思想、体现学生思维能力的一系列好题,物理教学中通常称为传送带问题.传送带问题可以综合考查运动学规律、牛顿运动定律、能量转化和守恒定律等物理力学的重要规律,考查学生研究对象的选取、运动分析、受力分析、选择规律的解题基本技能,是培养学生综合分析能力不可多得的好题.在此类问题中,学生解决问题比较困难的是传送带传送多个物体时,电动机的输出功率问题.下面举例
According to the actual situation of conveying objects by the conveyor belt, a great deal of good questions about physical thinking and students’ ability to think are designed in high school physics, self-enrollment and competition counseling. The problems in the physics teaching are usually called conveyor problems. Kinematics law, Newton’s law of motion, energy conversion and conservation laws and other important laws of physical mechanics, examining students’ selection of the object of study, motion analysis, stress analysis, choice of law to solve the basic skills is to train students comprehensive analytical skills In such issues, students solve the problem is more difficult to convey the conveyor belt when the number of objects, the motor output power problems. The following example
