Schnurmann 1 has shown that the results of measurements of static friction on naked cadmium surfaces at temperatures down to — 100° C. indicate that abrasion cannot be the only factor ...

The collective behaviour of the asperity ensemble that composes a frictional interface therefore determines the transition mechanism from static to dynamic friction. A complete understanding and ...

However, if you try to slide the mug across the table then a friction force will come into play and initially resist your push until your pushing force exceeds the frictional force. In other words, in ...

As a result, and perhaps counterintuitively, the surface starts sliding more easily, and the relative resistance to motion—the so-called static friction coefficient—decreases. Using a simple ...

Save guides, add subjects and pick up where you left off with your BBC account. Ice causes very little friction, which is why it is easy to slip over on an icy day. However, this is a good thing ...
