Anyways, doesn't it hurt because you get burned? Either by the extremely hot arc and/or the electrons flowing through your body encountering resistance?
You're probably right. Like I said, I don't much much on the topic of e- movement. Only need to know that for infrastructure design (well, I suppose grid design).

Yeah. Glad we are on the same page there.

I'm familliar with it. Well think of it as an impact transfers energy from the projectile to the nerves in your body. It can't really transfer the momentum (too much momentum wwould mean piercing and then a direct transfer of energy, rather than transfering through the skin and any gear/cloths).
I think it's safe to say that both momentum and energy can be attributed to pain, but moreso energy than momentum.

Hmmm. I like it, pain in the name of science (which isn't exactly a new thing).

Out of Sport. Have Fun!
