Energy is 'lost' or not used effectively when frictional forces occur. For example, when a bike applies its brakes and slows down the kinetic energy of the bike is transferred into heat energy in ...

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

The recent developments in understanding friction and the leading factors that determine the frictional response ... take place — using, for example atomic force microscopes (AFMs) for ...

For example, these so-called non-Newtonian fluids ... scientists must therefore understand the magnitude of the frictional forces between the individual particles. ETH materials researchers ...
