摘要

在两个独立的实验中研究了沿垂直平面上弯曲轨道滑动或滚动的物体。其中一个是一个光滑的金属螺母，它沿着由衣架线制成的半圆形轨道滑动。另一个是关于沿弯曲轨道滑动和滚动的台球。提供了一个简单的理论模型来解释结果，并将讨论扩展到考虑圆形轨道的最短下降时间。

Sliding and rolling along circular tracks in a vertical plane

Objects that slide or roll along curved tracks in a vertical plane are investigated in two separate experiments. One concerns a smooth metal nut that slides along a semicircular track made from coat hanger wire. The other concerns a billiard ball that slides and rolls along a curved track. A simple theoretical model is provided to account for the results and to extend the discussion to consider shortest descent times down circular tracks.

期刊介绍： The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
