The recent developments in understanding friction and the leading factors that determine the frictional response at the nanoscale (see Fig. 1), were the main topics of debate at the recent Trends ...

If you’re a fan of the Amnesia series, but haven’t played the brilliant Soma, now’s the time to take the plunge. Soma is an astounding 90% off on GOG, making it £2.50 / $3.16 for the DRM ...

Who knew brakes were such a hassle? According to the patent description, "Mechanical, frictional brakes, such as hydraulic brakes, add cost and weight, which can impact the performance of a ...

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 transformed into heat energy in ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

However, as the skydiver's speed increases the frictional force due to air resistance also increases. There comes a point when the skydiver's upward frictional force equals the skydiver's downward ...

Six parameters that could potentially influence the frictional forces, were considered: (1) the sports surface, (2) the shoe outsole cleat design, (3) the weather conditions, (4) the weight, (5) the ...
