Measuring Speed (In)dependence of Dry Sliding Friction.

The article explores the assumption in introductory physics courses that dry sliding friction is independent of the relative speed of contact surfaces. The authors conducted experiments to determine if sliding friction force depends on sliding speed, using different materials and padding to minimize surface damage. Results showed that friction force can be considered independent of sliding speed, with the friction coefficient dependent on the normal force. The study provides valuable insights for physics education and suggests further research possibilities in the field of sliding friction. [Extracted from the article]
