Unit of Angular Velocity

    The unit of angular momentum is kg * m^2 / s (or I * W). The moment of inertia for a point mass, mr^2's unit is kgm^2. That means the unit of W has to be 1/s. I'm having trouble converting this to radian/s.

    Thank you!

    Has the child stopped moving?
    It is already rad/s.
    Radians and degrees are a bit strange in that they have units but, conventionally, not dimension.
    As it happens, I wrote an article on this: https://www.physicsforums.com/insights/can-angles-assigned-dimension/

    Since the child moves with the merry-go-round, we have to consider a separate moment of inertia for Lindsey, right?

    Yes.
