Let’s say we have a micro-gravity environment where people are staying afloat in the air because they have wings or some other means of resisting the low gravity, but then for some reason they find themselves bereft of that ability and start being pulled by the gravity… would they break their legs or be killed outright when they fell to the body generating the gravity, even though the gravity is low? How would that be calculated?
I am thinking of a dwarf planet with the same mass and gravity as Ceres. This planetoid has an earth-like atmosphere (hand wave that part for now). Characters there can float/fly, but an accident creates the scenario where one is lost and is being pulled by the gravity. What happens when he/she finally “crash lands”?
Here's the scenario in more detail: human astronauts find this microgravity environment. Small planetoid/dwarf planet, approximately the size of Ceres, that has an atmosphere that is just like Earth's (again never mind how). The creatures there can keep afloat in the sky with their wings.
One of the astronauts goes exploring using a "jet pack" to fly around. A creature attacks him, damages the jet pack, and the astronaut is left with no means of getting around. He's just floating there. No one comes to his rescue. Sooner or later the gravity, though low, does pull on him and he starts "falling".
Barring a rescue or any ability of his own to "float/fly" what happens next? When he hits the ground does he go splat or does the lower gravity give him any chance of survival?
