The motion of a curling stone is controlled by the frictional interaction between its running band and pebbles on the ice sheet. This paper calculates the net friction forces and torques by use of the evaporation-abrasion model, and shows that the ice friction coefficient on the rear running band is by a factor of A larger than that of the front. The curl ratio was introduced to describe definitely the curl distance as a function of translational and angular velocities of a stone.
