In general, getting into this position is nearly impossible once youre free falling. Spiders, snakes, the dark these are called natural fears, developed at a young age, influenced by our environment and culture. Then, we can relate speeds to equivalent heights, using some Newtonian mechanics: speed = (2 g height), where g is acceleration due to gravity. If you're standing upright, it'd all be transfered through your legs; as Flaviu mentioned, laying down so the force is spread across a larger area would be a better option to this. Clearly, this is not a conserved quantity, but the point is that it only depends on the external gravity field, not on the interaction between human and elevator. Say you were in an elevator, in a free fall. Impact severity is largely defined by the shortness of stopping distance. b. its acceleration is zero. Trapped air in the shaft below the elevator may provide an additional cushion.

During the free fall C) zero because the car is not accelerating. If he jumps at a height of $h$, his potential energy will be $mgh$ and his kinetic energy will be $mg(H-h) = 0.5mV^2$ where $V$ is the elevator (and human before jumping) velocity, taken as a positive number so that $V=\sqrt{2g(H-h)}$. So, as much as wed all love to believe this is the best, easiest way to survive a disaster like this one, it is simply impractical. #fca_qc_quiz_51486.fca_qc_quiz button.fca_qc_next_question { Momentum is nothing but the product of your mass and velocity.

Denoting the total height of the fall with $h$, we obtain, $$ \frac{E'}{E} = (1 - \sqrt{h_1/h})^2 .$$, Thus, if a human is athletic enough to jump $1m$ in normal circumstances, then he might hope to reduce the impact energy of a fall from $16m$ to a fraction of, $$ \frac{E'}{E} = (1 - \sqrt{1/16})^2 \approx 56 \% .$$. @Greg Graviton - or alternatively, simply wait until you're in reach of the ground and use your leg muscles to push against it, thus transferring momentum to the Earth. }. This is called free fall, and it is this acceleration which results in the sense of weightlessness. Nowadays, elevators are crafted with special technology to help prevent accidents like from happening. Gravity is space bending and stretching like taffy. If this happens, the car can plunge multiple stories at shockingly fast speeds, potentially tossing passengers around the elevator. These cables very rarely snap, and inspectors regularly look at them for wear and tear. } Even if you lay on your back, equally distributing body weight in a crashing elevator, you could still be harmed. The falling human cannot change the total momentum of the system, but by jumping, he can. It seems more practical to jump up at 30 mph (partial impact cancellation) which can effectively cut down the 'g' forces by distributing the braking distance, sort of like the last second "braking" rockets of cosmonaut space craft that fire just before a parachute landing.
