Energia - Uma Propriedade dos Sistemas

Summary: In this animation interactively learning object movement present a girl initially along a curved ramp in the form of a slide, and then along a horizontal plane. This movement happens in such a way as to provide a variation of kinetic and potential energy along the ramp, where we consider the coefficient of kinetic friction between zero ramp and the girl, and this situation arises as a conservative system. Horizontally left open and under the user's control the insertion of friction on the flat surface, and the variation of intensity of friction between the girl and the surface, and the existence of friction this situation arises as a dissipative system. This dissipative system gives rise to discussions about the degradation of energy, possible irreversible transformations of energy.
