Okay, so I was running the other day and thinking about friction as I hit a patch of gravel. I'm a new physics student so I know enough to think about some things but not enough to know the answers yet. Why is it that if friction works to slow down my velocity, then when there is less friction (ie...I hit the gravel as opposed to the dry pavement) why don't I go faster? I can't go faster on loose gravel....just trying to make a connection here. Thanks for your input!!!
