In this study, a attempt has been made to simplify the role of tractive effort in applying driving force to overcome the resistances to motion of the automobile. Further, energy is stored in the automobile by virtue of its motion, which is termed Kinetic Energy. An analysis has been made on forces on car in a frontal crash. A comparison of forces on driver in a frontal crash (with or without non-stretching seat belt and with stretching seat belt) has been made. It has been concluded that there is reduction in fatalities if a driver wore a stretchable seat belt. Further, the occupant of the less massive vehicle is more at risk when a collision does occur1-2
