G-Force Calculator

One g is 9.80665 metres per second squared, so a g-force is just an acceleration divided by that number. This takes four routes to it: a speed change over a distance, the load factor in a level banked turn, the relative centrifugal force of something spinning at a given radius and rpm, and the average deceleration of an impact after a fall. None of them needs a mass, because mass cancels out of every one. The braking and impact figures are averages over the stop, and a real peak runs higher.
