Angular momentum vector

  1. Mar 31, 2014 #1
    A bicycle is traveling North. The direction of the angular momentum vector of it's front wheel is?

    I chose "North." The answer is West. Why?

    Look up right hand rule for vector products.

    The direction is given by the right hand rule.

    [itex]\hat{L}= \hat{r} \times m \hat{v}[/itex]
