The relationship between closing speed and both delta-V and kinetic energy loss in a vehicle collision is examined. Both delta-V and the total kinetic energy lost are related only to the closing speed, vehicle masses and the collision restitution, but those relationship are not the same. Collision severity is usually different for each vehicle in a collision because of their differing masses. Consequently, delta-V and the kinetic energy lost by each vehicle are measures of collision severity but the total energy lost in the collision is not because it combines the losses from both vehicles.
