Figure 1: Scheme of a typical experiment to study friction at the nanoscale, in which an AFM tip is driven along a surface. One of the main challenges in the field is linking the results obtained ...

Several experiments were exhibited to show the excitement of electricity by the least possible friction ; among which the most curious was the divergence of the gold leaves of an electrometer by ...

showed that it is the friction between the balls themselves and between the balls and the barrel that makes the barrel fly. Various attempts at explaining this experiment had already arisen on ...

He describes how friction opposes or prevents motion, and demonstrates the force in action with an experiment involving two interleaved books. Students could try to recreate this fun 'friction ...

OK, so friction occurs when two surfaces move over ... following presenters Mwaksy Mudenda and Greg Foot as they use demonstrations, experiments and animations to learn about forces and electricity.

In the past many experiments (Nikuradse, 1932 ... despite the vast amount of data in publication it is difficult to find satisfactory agreement (on friction factor and turbulence intensities for ...
