My wife that run a grade 10 outdoor head program use our sled made of UHMW and the one I made for the school that are identical but made out of HDPE and she always come back saying that our sled is way easier to pull than the school sleds. I tried as well and I find the UHMW glide more easily than the HDPE sleds! Also I found that the UHMW is more scratch resistant than the HDPE version...
do the same experiment, but on a gentle slope such that no pulling is required; just let them go and see how far they slide. That way the force applied to each sled is identical, instead of being merely similar, and you wouldn't need 1000 pounds either.
temperature is a variable here too
