Question

“It’s not the fall that hurts you; it’s the sudden stop at the bottom.”  Translate this saying into the language of Newton’s Laws

anonymous · Answer

that means that if you fall into huge gas ball you won't get harm.
it is the second law of newton:
$$F = ma = \frac{ \Delta P  }{ \Delta t }$$
when there is sudden stop the the acceleration is too high , so the force is also high.
when there is sudden stop the time required to change the momentum is so low,so you will get huge force.
