At what height would a fall most likely inflict injury?

Question

Eg. Double an individual's height? Kamehameha x 10?

Answer 1

Height is not the decisive factor in the injury sustained from falling. *** with most injuries, damage is resultant of speed, i.e. momentum, that the body undergoes before coming to a halt, meaning colliding, with some other surface.

Think about. Little old ladies can fall 3 or so feet and break one of the largest bones in the body, their hip. It's not because the fell a great height, it's because of the amount of force to which they collided with the floor, all resultant from their momentum. That's why people can fall off of bridges and live (water, a variable medium, absorbs some of the impact, thus lessening their momentum), while other people die from falling off a ladder, only 8 or 9 feet up (the Earth is a hard surface).

Also, don't forget the angle of impact: a fall from greater distance can result in fewer injuries if one falls on their feet, or arm, as opposed to falling from shorter height, but landing on the skull or spinal column.

I know what you're asking but the height doesnt really matter...

You could break your neck and never walk again from tripping over your shoelace....
