Hi everyone, My roommate and I were talking about which would win in a short downhill race (with no pedaling from either rider), a bike or a skateboard. Assuming the bike stays in the same gear (2, and 4), and has a wheel diameter of 27", and the skateboard has a wheel diameter of 2.4". My thinking is that the skateboard will accelerate faster very briefly, as it has the smaller wheels, but then the bike will catch up and surpass the skateboard before the end of the hill, assuming they start at the same point, and the start of the hill. Can anyone offer me any insight? I'll try to answer any questions for detail that I can. Thanks! Keaton Disclaimer: I'm not very knowledgeable in this field, but I'm really curious about this. I also wasn't sure about which prefix, to use, it's probably more high school level, but oh well.
