In these equations, e refers to elasticity or coefficient of restitution--the ratio of relative speeds after and before a collision--varying between 1, a perfectly elastic collision, and 0, a perfectly plastic collision.
From an ecological point of view, an elasticity value within this range could be expected, since perfectly elastic collisions are seldom observed and near perfectly plastic collisions are much more frequent.
where k is coefficient of collision (impact), within the interval from k = 0 for ideal plastic collision to k = 1 for ideal elastic collision (impact), and n is the number of impacts until the system is returned into the equilibrium position.
