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 is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor, friction makes this difficult.

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 ...

Although humans have been harnessing its power since rubbing two sticks together to build the first fire, the physics of friction remain largely in the dark. Now, Brandeis research is showing that ...

The answer to that question depends on the height at which the force P is applied to the block and on the coefficients of static friction at the feet. We need to work out the problem two times in ...

The recent developments in understanding friction and the leading factors ... and tribology tests take place — using, for example atomic force microscopes (AFMs) for nanotribology and pin ...

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 ...
