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 ...

This acts when an object is at rest and prevents it from starting to move. It increases up to a certain limit as you apply an external force to initiate motion. This acts when an object is already in ...

(Phys.org)—Many people are familiar with the friction enigma of two interleaved phonebooks, in which all of the pages of two phonebooks are overlapped, one by one, with the books' spines facing ...

It's perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some sort of ...

While many of us are treading carefully to avoid a slip in the frosty weather, scientists led by the University of Leicester have been investigating how to make surfaces even slippier! They have ...

For a number of years videos have been circulating the internet showing an intriguing experiment, which has now received a satisfactory physical explanation. In the video, a plastic bottle with a bit ...

I always enjoy MythBusters. Great material for blogs. Also, one of the things I like is that Adam and Jamie are not professional scientists. This means that if they make some mistakes, that is just ...
