Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

If there's one component on any vehicle which influences its handling characteristics more than anything, it's the tires. Tires are, in ideal situations, the only parts of a car that touch the ground, ...

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 ...

For the first time, ETH Zurich Materials Scientists have measured the rolling friction of microscopic, micrometer-sized particles. These measures allow them to better understand common items like ...
