Watch this video to learn more about friction. Find out about different types of friction and how we can increase or reduce it. Friction is a force between two surfaces rubbing against each other.

Friction can be a car’s best friend on a ... Students could then conduct an experiment to test their trainer on a range of different surfaces. As a class, students could decide upon four or ...

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 ...
