The Friction Pad for Vernier Dynamics System is for use with the original Vernier Dynamics System (2005-2015). It is not compatible with the Vernier Dynamics Cart and Track System (2016-present).
After working hard to make our dynamics carts very low friction, we’ve now added some friction back, so that you and your students can study friction in a controlled way.
Add a Cart Friction Pad to your Vernier Dynamics System, and watch the carts move under very consistent friction force. Setting the friction amount is as simple as turning a knob.
