This paper presents theoretical and experimental research explaining the retrograde final-stage rolling of a disk under certain relations between its mass and geometric parameters. Modifying the no-slip model of a rolling disk by including viscous rolling friction provides a qualitative explanation for the disk's retrograde motion. At the same time, the simple experiments described in the paper fully compromise the drag moment as a key reason for the retrograde motion considered, thus disproving some recent hypotheses.
