11. if you are not wearing a seatbelt and are in a collision, the force can eject your through a window.
12. friction + a human body + high speed = lots of pain and bleeding
13. the laws of physics dictate that when two bodies of mass collide the kenetic energy is transfered. when a high mass body collides with a low mass body, the force to mass ratio is skewed in that the effect is greater on low mass body, even though the same force is put on both bodies. in this instance, a several ton tractor-trailer traveling at high speed collided with a slow moving car which was less than a single ton. the result of the two colliding was that the car was rocketed forward.
My message:
the laws of physics are something you can never break.
