3d dynamics rotation/inertial formula question

  1. Dec 6, 2012 #1
    1. The problem statement, all variables and given/known data

    I just saw the equation R'=RΩ (where ' is dot, or the derivative) in my notes (unorganized obviously), and can't remember what it stands for (rotation matrices?).
    Can somebody please tell me what this equations means thanks. I know R is some position vector and Ω is the angular velocity, but I don't get what this equation is saying. Thanks.

    2. Relevant equations

    3. The attempt at a solution

    For Circular motion, the tangential velocity (m/s) = radius of circle (m) x angular velocity (radians/s)
