COLLISION BETWEEN TWO RIGID PARTICAL in one dimension In any type of collision(elastic, non elastic and compete inelastic) the Ecentrycity(e) is equal to ratio of sum of modulus of after collision velocities(v1 and v2) and sum of modulus of initial velocities(u1 and u2) of two partical. e = |v1|+|v2|/|u1|+|u2|
