I’m not sure it’s physics that’s relevant here, but rather biology. Ignoring the window slamming for the moment, you have flying creatures about 4-6 inches tall with tiny wings. So you’d expect lightweight, hollow bones, but quite muscular and resilient. Think of a sparrow or small owl hitting a window. The impact of the wall might put them out for a bit, but assuming no broken wing or neck, they usually sit around dazed for a bit and then fly off.
Not around my office. There are people working on the issue, but we’re guilty of a lot of bird deaths.
It might also be worth noting that birds’ bones generally knit very quickly.
For that matter, do fairies even have bones? I don’t know, but you should really make up your mind on things like that, if you’re going to go on with the comic.
Of course they have bones! They’re tiny, anthropomorphs! With wings and a ‘can do!’ attitude.
I could see them having hollow bones, if needed. There’s some logic to that. But there’s no logic, such as the comic has, in them being anything other than a rough approximation of small-scale humans.
Hell, in one comic we see Newton delivering a fairy-fu (forgive me) kick to the witch. That implied both muscle and bone.
And, of course, one Newton of force.
The wings appear to be thin membranes like insect wings, rather than bone and feather. That suggests a form of fragility. Depending on positioning, there might have been wing damage from the wall impact. But if the wings were not moving, and he was traveling essentially back first from the swat, then most likely the wings were trailing, and thus not crumpled. Depending on how flexible they are and body position of hitting the floor. Meh, I’ll give him the benefit of the doubt and suggest the wings are okay.
An impact strike, bruise to the body, concussion from the original blow is what caused the unconsciousness. Possible whiplash. Whiplash will make his neck really sore, maybe need a brace, not want to turn or move it much.
OK, if that’s the way it works in the comic, that’s fine. But I could also imagine fairies as being only superficially anthropomorphic, and actually having insect-like exoskeletons, or being homogeneous inside with no particular anatomy, or being some completely different shape entirely and merely appearing human due to use of illusions, or whatever. There’s no “of course” about it.
Alia and I had discussed exoskeletons, believe it or not. But there’s nothing in the comic to suggest such, or even that the fairies are anything other than magic tiny humans with wings. So that’s what we’re going with.
