Rolling friction - models and experiment. An undergraduate student project.
Original language description
In this paper the model of the rolling friction (rolling resistance) is studied theoretically and experimentally on the undergraduate level of the fundamental course of general physics. Rolling motions of a cylinder along horizontal or inclined planes are studied by simple experiments, measuring deformations of the underlay or of the rolling body. The rolling of a hard cylinder on a soft underlay as well as of a soft cylinder on a hard underlay is studied. The experimental data are treated by the open source software Tracker, appropriate for the use on the undergraduate level of physics. Interpretation of results is based on elementary considerations comprehensible to university students ? beginners. It appears that the commonly accepted model of rolling resistance based on the idea of a warp (little bulge) on the underlay front of the rolling body does not correspond with experimental results even for soft underlay and hard rolling body.
