Ice skating is based on the phenomena of reduced friction. Explain briefly.
Asked by Topperlearning User | 6th Jun, 2014, 08:34: AM
Ice skaters actually move on a layer of water, and don't skate on ice at all. When ice is subjected to high pressure it melts. The narrow blades of the skates create a very high pressure and thus the skaters glide along on a layer of water that has just melted. The water refreezes as soon as they've moved on.
