You'll have to excuse me - I'm nothing close to a physics expert. I have a friend who was in a car accident. I was told they were going a couple of G's when they entered into the spin (the car flipped end over end). For argument's sake, lets say they were going 2 or 3 G's. Can someone explain to me what exactly this means and put it into idiot terms? And what could happen when going that fast? Two people were thrown from the car, and all the passenger's shoes stayed in the car. Thanks!
