Reconstruction methods typically are based upon impact velocity changes computed by one of two approaches. These are damage based or crush measurement techniques and impulse and momentum equation solutions. Crush measurement techniques have an analytical foundation based to a large extent on point mass collision theory, limited primarily to collisions of vehicles with a common final velocity at the contaact surface. Impulse and momentum methods can treat a full, 2-dimensional collision with arbitrary restitution and friction coefficients. As such their analytical foundation is much broader than damage based or crush measurement methods. The energy loss relationship and the tangential correction factor form an important part of the crush measurement methods. These two relationships are derived in a more general fashion than has been available.
