Skating on slippery ice
LION, Universiteit Leiden, Niels Bohrweg 2 – 2300 RA Leiden – The Netherlands
Skating has been popular for centuries but is still poorly understood. Is it sufficient that the surface of ice is wet in order to explain why skating is possible for a wide range of temperatures, velocities and types of skates? Or do we need a layer of water formed between skate and ice by the frictional heat? Here we discuss the physics of the water layer and its implications at large velocities as occurring in speed skating.
