Show that static friction is greater than kinetic friction by pulling on a wooden box using a spring scale. Clamp the board to a table. (Optional) Select the 50 N scale on the force probe and connect ...

Learning the 'effective' notions of static and sliding friction, students of mechanics ... of the order of 10 −11 kg s −1. Many other experiments, including recent work with polymer thin ...

Figure 1: Scheme of a typical experiment to study friction at the nanoscale ... Atomic force microscopes typically operate at sliding amplitudes of a few micrometres, whereas macroscale testers ...
