I know if I apply a force(perpendicular to he radius) to a wheel to rotate it, I am applying a torque. I change the wheel's angular acceleration, thus creating a torque. I can find the direction of a torque via the right hand rule. If there is a wheel spinning in space where there are no forces acting on it, does the wheel still have a torque? ([tex]\tau[/tex] = L[tex]\alpha[/tex]) Doesn't the wheel still have an angular acceleration? I'm afraid I've been thinking about all of this too much and am beginning to confuse myself.
