But the velocity dif-ference after impact will be greater asthe coefficient of restitution approachesunity. In other words, the greater theelasticity the greater its recoil or kickback, and therefore the greater accumu-lative velocity difTerence between suc-ceeding cars and. correspondingly, thegreater will be each collision as the slackaction passes on through the train. In this connection it is impossible todissociate the two phases of elasticity—the involving restitution of form andenergy and the other involving themodulus of elasticity, or unit stress(force per unit area) per unit elongationwithin the elastic limits. Every sub- 1 IWO comparatively small stress will take itlieyond the elastic limit and break it. .\s the elasticity of a substance isgreater, the elongation for a certainstress is less and the give or cushion-ing efT
