Why do gymnasts feel G-forces more intensely than astronauts?
Quick fact
Gymnasts' lower bodies withstand peak impact forces of over 10,000 Newtons upon landing, equivalent to having a small car dropped on their legs for a split second.
Why this is interesting
When a gymnast lands a double backflip, their joints momentarily experience a force up to 14 times their body weight—that's more than a space shuttle launch.
