Abstract
An apparatus which damps oscillation in a ski, the apparatus comprising an enclosure, a cavity encompassed by the enclosure, and an aggregate located in the cavity. The cavity has a dimension in a direction perpendicular to a gliding surface of the ski which is larger than a thickness of the ski in a location adjacent to the enclosure. The aggregate, in its tapped density, occupies substantially less volume than a volume of the cavity, thereby allowing significant travel of the aggregate in the cavity. Oscillation accelerates and decelerates the enclosure, resulting in accelerations and decelerations of the aggregate which cause it to acquire and lose kinetic energy. The aggregate's acquisition and loss of kinetic energy attenuates the oscillation.
