@bowman81 Exactly. But the stop kills you because of the force of impact, and this decal shows the formula for force = mass times acceleration (rate of change of velocity)
@bowman81 it is the speed at which you suddenly stop. If you suddenly stop at a speed of 1 mph it's not going to kill you. But if you stop at a speed of 100 mph it will kill you. So it is a combination of speed and suddenly stopping
