A bowling ball on a cable is hung from the ceiling. When the ball is pulled back and released it will move like a giant pendulum returning almost to its starting position. This demonstrates Conservation of Energy. There is a small loss due to friction and air resistance so the bowling ball will not make it all the way back to it's starting position.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
