We perform calculations for different systems to study the mass dependence of flow disappearance in heavy-ion collisions in a relativistic Vlasov-Uehling-Uhlenbeck approach based on Walecka's [sigma]-[omega] model. We find that the mass dependence of the energy of vanishing flow is the result of a complex interplay among the momentum dependence of the nuclear mean field, Coulomb potential, and [ital n]-[ital n] collisions. The effect of the [ital n]-[ital n] collisions is predominant and the particular scaling value ([ital A][sup [minus]1/3]) of the mass dependence can be related to the scaling behavior of the collision number per nucleon.
