A visual explanation of the brachistochrone
A two-dimensional animation compares descents on a line, circular arc and cycloid. Shared endpoints and timers distinguish distance from travel time.
Reference prompt
An edited reference based on this example. Adapt it to your subject; the creator’s post is linked in the source panel.
“Explain the brachistochrone problem with a two-dimensional animation. Between the same starting and ending points, simultaneously show balls descending along a straight line, a circular arc, and a cycloid. Use paths, timers, and brief annotations to explain the difference between the shortest distance and the shortest travel time.”
