For a real world problem, I've been puzzling over the trend to go after very light-weight rims for bicycles. My BS in physics hasn't provided me with solid answers. I am a bit rusty.
I have found a feeling of increased stability when running heavier rims and attributed this to an increase in momentum. That said, many fellow riders have said I am having to expend considerably more energy to keep these heavy rims moving forward, esp. when going up a hill.
Most of the information I have found on the relationship between momentum and energy refers to relativity and small particles. Please help me out here.
Thank you,
Katie
