Quick Answer:The KE PE Track is a dual-path track on a wooden base for showing how a ball’s gravitational potential energy turns into kinetic energy as it rolls down, with a built-in scale for measuring drop height and horizontal displacement.
Last updated: 18 October 2026
Key Features
Two paths, one straight and one cycloidal slope, for comparing descents.
Track in PVC or metal, mounted on a reinforced wooden base.
Stainless steel or nylon balls.
Integrated scale for drop height and horizontal displacement.
Supplied ready to use.

Scale
Integrated, for drop height (h) and horizontal displacement
How It Is Used
A ball released at the top loses height and gains speed, so the drop read from the scale can be linked to the motion it produces. Running the ball down the straight path and then the cycloidal one introduces the brachistochrone problem, in which the curved route gives the quicker descent even though it is longer.
Frequently Asked Questions
What can be measured on the KE PE Track?
The integrated scale gives the drop height of the ball and its horizontal displacement, so the loss of potential energy can be compared with the motion that results.
