1J20.70 - Rolling Uphill

Code Number:
Demo Title:
Rolling Uphill
Exchange of Potential and Kinetic Energy
Area of Study:
Wooden Track (Non-Level), and Double Cone for Wooden Track.

Move the cone to the end of the track and let it go, it will appear to roll uphill.  However, if you observe the axle of the cone you will see that it is actually traveling downward.
