Hey guys, I'm a student at high school in Australia. I currently have a physics assignment that states i have to explain the forces and physics of an object. I have chosen cycling. I know the basic s=d/t and a little bit on airflow and using the "teardrop" shape in helmets and frames, but otherwise i'm a bit stuck on what concepts to explain and use in my paper. I can explain stuff about the equipment (clothes, helmet, frames, cleat-shoes) or the speed, drag, momentum, terminal velocity etc (like formulas, they could be really helpful!) Any help on anything to do with cycling and physics would be greatly appreciated. Thanks all the way from oz. Nels.
