• Although current equations for coefficient of restitution in the central impact of solid spheres were presented only empirically as a function of the impact velocity v., theoretical equations for the coefficients of restitution as a function of v_i for the impact of spheres of equal diameter and equal material are presented in this study under the assumption that the separation of the impacting spheres is determined at the zero relative displacement. Through comparison of results measured here using two ball pendulums for spheres of brass, lead, glass, porcelain and agate, the viscous nature of the materials is estimated.
