Descending from A to B along the Quickest Path
Physics Education, v57 n5 Article 055029 Sep 2022
A simple experiment is described to compare the descent time between two vertically separated points when an object slides down tracks of varying shape. A surprising result is that the descent time is shortest when it follows a circular track rather than a cycloidal track. Cycloidal tracks are usually predicted to result in the shortest descent time, but only if friction is negligible.
