For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and ...

Coming from the days of block chalk (I’m a child of the 1980s), I often find myself gravitating more toward thick, chunky chalk even when it comes in bag form. The fine, powdery stuff befuddles me, ...

The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers at the University of Illinois Urbana-Champaign led by professor Rosa ...

For people who say “chalks just chalk” Friction Labs will change your mind. Recently a team of world-class geologists and chemists conducted independent tests on the five most common chalks for rock ...

Your objective today is to measure the coefficients of static and kinetic friction between a block of wood and a ramp. We already learned that frictional forces resist the motion of an object, and ...

Friction Labs, a local athletic chalk company, is introducing their Cause Good initiative to Denver. This month, children from Boys & Girls Clubs of Metro Denver and Denver Children’s Home will be ...
