竖直平面内的圆周运动是圆周运动中的重要类型,约束物及其条件不同,竖直平面内的圆周运动可以是匀速圆周运动,也可以是变速圆周运动。中学物理教学大纲中规定,对竖直平面内的变速圆周运动,除最高点和最低点之外,不要求定量讨论,亦即对其它各位置仅限于定性分析,本文主要分析以轻绳和轻杆作为约束物的竖直平面内的变速圆周运动及其应用。
The circular motion in the vertical plane is an important type in circular motion. Constraints and their conditions are different. The circular motion in the vertical plane can be uniform circular motion or variable speed circular motion. The syllabus for middle school syllabus stipulates that except for the highest point and the lowest point, the circular motion in the vertical plane does not require quantitative discussion, that is, it is limited to qualitative analysis of other positions. This article mainly analyzes the use of light ropes and light weights. Variable speed circular motion in the vertical plane of the rod as a restraint and its application.
