The paper deals with the low-speed impact of rigid bodies. The elasticity and damping forces, acting on a body during the impact, depend on the physical properties of the material; in this work these forces are considered according to the Kelvin–Voigt, Bingham and Maxwell models of the medium. New models of the forces, acting during the impact, are elaborated. Numerical solutions of the equations for various impact forces are obtained.
