Quick Answer:The KE PE Track Model has a straight slope and a cycloidal slope side by side, with a steel ball, for showing the change from potential to kinetic energy and the curve-of-fastest-descent property of the cycloid.

How It Is Used
Comparing runs on the straight and the cycloidal path shows the brachistochrone property: the cycloid gives the quicker descent although it is the longer route. The track also lets students connect the height lost, PE = mgh, with the speed gained, KE = ½mv².
Frequently Asked Questions
What paths does the KE PE Track Model have?
Two: a straight slope and a cycloidal slope, so that motion down the curve of fastest descent can be compared with motion down a straight incline.
