Imagine a heavy book resting on a table. If you try to gently push the book across the table with the tip of your finger, it ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Atomic force microscopes typically ... the asperity ensemble that composes a frictional interface therefore determines the transition mechanism from static to dynamic friction.

Learning the 'effective' notions of static and sliding friction ... For example, measurements of the force required to drag the aluminium tip of a scanning tunnelling microscope over a gold ...

However, this is a good thing for ice skating and sledging. Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a ...
