Homework Help: Wat are the units of angular velocity of precession?

  1. Nov 19, 2007 #1
    1. The problem statement, all variables and given/known data
    What are the units of angular velocity of precession? Ive looked evrywhere and can't find out.

    2. Relevant equations

    3. The attempt at a solution

    In my answer to a question, by putting units into the equation i think im getting units as rad^-1 s^-1 but not sure if it should be rads per second.

    [tex]\boldsymbol\omega_p = \frac{Q}{I_s\boldsymbol\omega_s}[/tex]

    In which [tex]I_s[/tex] is the moment of inertia, [tex]\boldsymbol\omega_s[/tex] is the angular velocity of spin about the spin axis, and [tex]Q[/tex] is the torque.

    Moment of intertia is mass times distance squared.
    Angular velocity is radians per second.
    Torque is newton-meters, or kilogram meters squared per second squared.

    I get the same as you:

    [tex]\frac{1}{rad\times s}[/tex]
