eli5 how does jumping before an elevator hits the ground not save your life?
In: 48
For the same reason that you can’t save your life in a crashing airplane by doing a little jump in the aisle just before impact, or rolling off the roof of a tall building with a skateboard under your feet and then jumping up off of the board just before ground. As others have said, the speed that you jump up does get “taken away” from your downward crash speed (if you time it just right) but that amount of energy reduction is insignificant vs what still remains.
