The paper considers two models used in dynamic analysis of multibody system, describing the collision behaviour. One of the models accepts the internal friction work and the other, the plastic deformation work, but the common parameter is the coefficient of restitution. The effect of the coefficient of restitution is presented comparatively, in graphical manner, upon the normal approach, relative velocity versus time dependencies and phase maps. Following the different hypotheses, the dynamical system evolutions are significantly different. The two models studied represent the boundaries of a domain within which the actual system behaviour could be placed and the necessity of a complex model as amalgamation of the two models considered is emphasized.
