The blocks have an inset where you can place a mass that acts as a counter-balance. You will need a small ball that is able to roll along the channel, a 3.1 cm diameter mass, Rotary Motion Sensor, and a rod stand.

  • Attach a block on the axle of a Rotary Motion Sensor.
  • Attach the channel to the block.
  • Spin the system up - observe that the ball remains at the top of the channel, and slowly rolls down as the system loses energy.
  • Place a ball on the channel and spin the system up.
