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. This device slides onto the end of one of our green metal dynamics carts, but is incompatible with our plastic carts. For use with the new style carts see Friction Pad DTS.
