 Acceleration is changing speed, actual speed is how fast something is traveling. As gingerbread put below, you can move extremely quickly provided you accelerate slowly to it. Changes in acceleration in any direction are what kill you; this is things like slamming your brakes on in your car, or a sudden impact. All of these things are sudden deceleration, which is what is actually killing you, not the actual speed you were traveling in first place.Acceleration is change in speed over time. Speed is distance traveled over time. So there are two Blue Devil Strong Girl Classy Sassy And A Bit Smart Assy Vintage Shirt ways to reduce acceleration (or deceleration). If your speed is very low to start with than even if you stop fast your acceleration is still relatively low, hence non lethal if you were just running. The other way to reduce acceleration is to increase the time it takes to stop. Hit a tree and it takes 1/2 second to stop from 60mph. Hit your brakes at 60mph and it takes 12 seconds to stop, very different accelerations, very different lethality.
