When u skate on ice and overcome the force of friction u generate energy or heat. This heat generated instantly melts the ice as a skater travels. But because of the refrigeration unit under ice, the section on which they just skated on, refreezes The trails when you skates quickly re-freezes once you have passed by.

The Physics Of Ice Skating Source: http://www.flickr.com/photos/coolmikeol/4054538571 For the most part, the physics behind ice skating comes down to analyzing the movement of skates over the ice. The skates do two things: They glide over the ice and they push off the ice with the edge, which causes a gain in speed. With practice, this combination of movements can become as effortless as walking. Another part of the physics is the low friction of the skate blade with the ice. This low friction allows a skater to easily glide over the ice surface, and in addition, the physical properties of the ice allows a skater to dig in with his skate in order to go around a turn, speed up, or stop. A skater...
