I have had this problem. Including the physics part. Well, the physics part isn't a "problem" though.
I also found that ponytail concentrated the location of the pull of the weight - giving me a similar headache. Grocery bag held with a single finger versus grocery bag held with the whole hand? Sounds like you don't have that problem.
