Abstract: A single particle rolling experiment was carried out on a slope with 100 steps. The relationship between the ball stop position and the size of the ball, the initial velocity and the step parameters were studied by statistical method. The equations of motion were described. And the semi-quantitative relationship between the rolling behavior of the object and the object scale, the initial velocity of the movement, the resistance coefficient and the rolling friction resistance was discussed. According to the statistical method, the corresponding fitting parameters are given and discussed according to the computer simulation experiment. The simulation results are in good agreement with the experiment.

Key words: rolling behavior, sidesteps, granular material
