The motion of a curling stone is controlled by the frictional interaction between its running band and pebbles on the ice sheet. In this paper more detailed results of computations of path trajectory, curl ratio, and effects of sweeping, pebble density and the level of ice sheets are reported. Curl ratio is a convenient quantity to specify definitely the direction of a stone to move at a given translational and angular velocities. It increases with the decreasing translational velocity and increasing angular velocity. Sweeping can be reasonably explained as warming of ice surface. The increase in the number density of pebbles leads to the decrease in the pressure acting on pebbles, resulting in the increase in the ice friction coefficient and curl ratio. Trajectories at various inclined ice sheets are computed and discussed.
