A simple one-dimensional microscopic model of colliding bodies is presented to understand the energy dissipation process. It is found that the COR depends on the initial velocity and is minimum at ṽ≃1. These behaviors are independent of the potential form. In low-velocity collisions, the relationship between the energy dissipation rate and collision velocity is derived using perturbation methods.
