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 ...

A spinning tool plunges into two pieces of metal, rotating at a high rate of speed. As the tool begins to move, it softens ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

Perhaps few physical concepts have received less attention relative to their importance than friction. Learning the 'effective' notions of static and sliding friction, students of mechanics can easily ...

You can't escape friction. The force that resists motion between two objects that are in contact with one another exhibits itself all over the place: in between your engine's rod bearings and its ...
