Summary

THE PAPER REVIEWS THE MECHANISM OF KINEMATIC FRICTION IN RELATION TO ICE AND SNOW PROPERTIES. FRICTION BETWEEN SKATE BLADES AND ICE DEPENDS ON THE ICE TEMPERATURE. WHILE THE HARDNESS OF ICE IS HIGH, ITS SHEAR AND ADHESION PROPERTIES ARE VERY LOW. COEFFICIENTS OF KINEMATIC FRICTION IN ICE SKATING ARE AS LOW AS 0.005. OPTIMAL CONDITIONS FOR RINK ICE ARE 271 K (-2 DEG C), A TRANSPARENT CONDITION, FREE OF AIR BUBBLES AND THE ABSENCE OF IMPURITIES. SNOW ON A SKI COURSE SHOULD HAVE A MINIMUM DENSITY OF 450 KG/M3 AND A HARDNESS OF 100 PASCALS. THE COEFFICIENT OF KINEMATIC FRICTION IS OFTEN AROUND 0.05.
