Use with Vernier Standard Cart and Plunger Cart
Study the effects of friction in a controlled manner and watch carts move under consistent frictional force when you add this accessory to your Vernier Dynamics System. Simply turn the knob to set the friction amount and observe.
Note: This Friction Pad is not compatible with our older metal dynamics carts that were part of our Vernier Dynamics Systems that were sold from 2005-2012.
