Why is ice slippery? When other substances such as metal or candlewax reach a temperature that solidifies them they are not slippery so why water? It is more slippery when wet, rather than when dry. (coefficient of friction = 0 = wet ice on wet ice) Clean smooth metal surfaces can be very slippery, as can some smooth stone floors. Smooth = slippery = no friction. -- Gianna Stefani www.buchan-meteo.org.uk |
