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 ...

Friction represents obstacles to change. Most people try to push through friction instead of reducing it.

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 ...

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 ...
