1.The change in momentum is greater in the head-on collision.
2.The momentum of the driver relative to the ground is greater in a head-on collision.
3.The velocity of the driver relative to the ground is greater in a head-on collision. 4.The average force on the driver is greater in the head-on collision.
5. The collapse of the crumple zone in the front of the car occurs only in the head-on collision.
