How is ski jumping not the same as falling from a 10 story building and how can a ski jumper's knee joint not crush?
Ski jumping is not the same as falling from a 10 story building because the skier has control over their descent. A skier can use their body weight and arms to adjust their position, and they can land on their feet instead of their head. This is why ski jumpers typically only suffer minor injuries, while people who fall from buildings often suffer severe or fatal injuries.
The ski jumper's knee joint does not crush because the impact of the landing is absorbed by the entire body, not just the knee. The skier's legs are bent at the knees, hips, and ankles, and their arms are extended in front of them. This helps to distribute the force of the impact over a large area, preventing the knee joint from being crushed.
