    "abstract": "We show that the friction force and torque, acting at a dry contact of two\nobjects moving and rotating relative to each other, are inherently coupled. As\na simple test system, a sliding and spinning disk on a horizontal flat surface\nis considered. We calculate, and also measure, how the disk is slowing down,\nand find that it always stops its sliding and spinning motion at the same\nmoment. We discuss the impact of this coupling between friction force and\ntorque on the physics of granular materials.",
