在考查圆周运动知识点时,往往会涉及圆周运动物理量间的关系,而此类问题经常以传送带或齿轮传动等情景出现,要求定量分析轮上不同位置的线速度、角速度和向心加速度等物理量间的比例关系。对于这个问题很多学生都感到棘手,因为物理量比较多,解决时各个量易乱且比较繁琐,易出错。下面介绍若干解决此类问 In examining the knowledge of circular motions, it often involves the relationship between the physical quantities of circular motions. Such problems often occur with conveyors or gear transmissions and require quantitative analysis of physical quantities such as linear velocity, angular velocity and centripetal acceleration at different positions on the wheel The ratio between. Many students find it difficult to deal with this problem because of the large amount of physical quantities and the ease with which the individual quantities are easy to handle and complicated. Here are some solutions to such problems
