THE CAR COLLISION
During a crash, the car crashes to a stop. At 30 mph, a car hitting an object that is not moving will crumple in about two feet.
As the car crushes, it absorbs some of the force of the collision.
THE HUMAN COLLISION
The second collision is the "human collision". At the moment of impact, passengers in the car are still traveling at the vehicles original speed.
When the car comes to a complete stop the passengers continue to be hurled forward until they come in contact with some part of the automobile.
For example, the steering wheel, the dashboard, the front window or back of the front seat. Humans in a crash can also cause serious injuries to other humans when they collide with each other.
People in the front seat of a car are often hit by rear-seat passengers as they fly forward with incredible force.
THE INTERNAL COLLISION
In a crash, even after a human body comes to a complete stop, its internal organs are still moving.
Suddenly, these internal organs slam into other organs or the skeletal system. This "internal collision" is what often causes serious injury or death.
Imagine what happens when someone's head collides with the windshield of a car. After the person stops moving the brain hits the inside of the skull.
The result may be only a mild concussion or there could be permanent brain damage.
