Abstract

Abstract: The Virtual Laboratory was created as a complementary educational activity, with the aim of working abstract concepts from an experimental point of view. In this work, the motion of a ring rolling and slipping in front of a grid printed panel was recorded. The frames separated from this video received a time code, and the resulting set of images can be visually inspected to determine the object angular and center-of-mass positions at known moments. From the positions versus time table, it is possible to analyse the dynamical evolution of the system and the ensuing physical interpretation of the ring rotation and translation. It is also shown here how this hands-on activity has been assigned to university students, that access the material from the websitewww.fep.if.usp.br/~fisfoto .
