Recently I found out about jerk (or jolt). I've found that it represents the change in acceleration over time. To me, this makes no sense at all. To me, the change in acceleration is directly related to the radial distance between the two objects (if the forces acting on or imaginary objects are due to gravity), and has nothing to do with time. I don't get why the fact that jerk is measured in change in acceleration over time will give the correct results if we for example, throw a 20g ball directly upwards from a 20kg planet whose radius is say, 100m, at two different speeds. The faster initial velocity will cause the ball to travel higher, therefore the change in acceleration being greater, and although yes the change in time will be greater, I just can't grasp why it works and how the change in acceleration is related to the change in time. Could someone please explain what is going on and why, or maybe point a very digestible tutorial, and try to avoid calculus if possible. Thank you very much
