    "abstract": "We examine the kinetics of a snowball that is gaining mass while is rolling\ndownhill. This dynamical system combines rotational effects with effects\ninvolving the variation of mass. In order to understand the consequences of\nboth effects we compare its behavior with the one of some objects in which such\neffects are absent. Environmental conditions are also included. We conclude\nthat the comparative velocity of the snowball is very sensitive to the hill\nprofile and the retardation factors. We emphasize that the increase of mass\n(inertia), could surprisingly diminish the retardation effect due to the drag\nforce. Additionally, when an exponential trajectory is assumed, the maximum\nvelocity of the snowball can be reached at an intermediate step of the trip.",
