"WebNo! ω is the angular velocity. And yes, usually, this is a vector quantity - but only if you use the "real" definition ( *ω* = r x v / r ² ). In your case, the argument has to be: dθ/dt = ω; Theta is obviously a scalar - cause θ and φ almost always are angles. Thus, ω is a scalar quantity in your case. So, θ does not have a direction.
