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 ...

They could then design and plan their own friction experiment. A marble race could be set up to explore the friction of different surfaces. Students could set up a ramp using a piece of wooden ...

Ice causes very little friction, which is why it is easy to slip over on an icy day. However, this is a good thing for ice skating and sledging. JavaScript is required to view this activity.

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 ...

But in instances where friction doesn't contribute to creative work, wealth advisor Kate McCallum has some advice. She encourages teams to take part in an activity called "brain writing" to get ...

"This means we need to rethink the fundamental basis of the fault mechanics used in forecasting the seismic activity of earthquakes." In the context of rock friction studies, the direct effect of ...
