Results show that the equivalent mass in normal direction depends on the modes of collision. In the case of reversed sliding and sticking, the coefficient of restitution varies as a result of the instantaneously changes of the equivalent mass during impacting process. The coefficient of restitution depends not only on the contact force, but also on the kinematical and dynamic parameters of the two rigid bodies. Moreover, a formula is proposed to calculate the coefficient of restitution.
