Ball Sculpture

Metal structure using rolling ball to demonstrate a variety of physics concepts

Balls roll along the undulating path speeding up and slowing down as they exchange kinetic for potential energy. The effect can be seen with the naked eye. The effect can also be quantitatively analyzed by filming it and then slowing down the frames to measure speed and elevation change showing that 0.5*mv2=mgh.

Balls are launched from a ramp and land on the ruled platform shown below. By measuring the geometry of the ramp, students predict the balls’ projectile motion. Students test their prediction by observing where balls land on the platform.
