Thats all I really needed to know. This started out as an argument between my cousin and I. We were both laying on the floor and trying to pull each other towards ourselves. I explained to him that the problem was that, not that I was not strong enough to pull him, but that I did not weigh enough. He weighs 230 pounds and I weight about 140. Every time I tried to pull him towards me, I just moved towards him. He kept saying, and actually believed it was because I was not strong enough. I set up many models to prove to him that he was wrong and that I was right. I would have loved to be proved wrong, but in this case I know that because of my weight, I could not have enough friction between myself and the floor. I really had no choice but to try and get someone else's opinion.
