Experiment Mk-02

Rolling and Sliding Friction

Description: A skate board is pulled across the lecture table so that it can roll or slide. The required force can be read on a large dial balance. This experiment will show that sliding friction is greater than rolling friction.


The skateboard may rolled, as shown above, which requires little force.


The skateboard may be slid, which requires more work than rolling.



Materials: skate board, dial-type spring balance, string
