What is the significance of gravity on the torque of balls rolling down an incline?
I know that gravity is able to exert a force, or torque by acting on the center of mass, causing an object to rotate. But what about rolling motion? Where would the axis of rotation be for a ball rolling down an incline?
Also, in terms of gravity, what does it mean for a ball to have a large/small moment of inertia and torque. Does this show anything about the effects of gravity on balls that have large/small moments of inertia and torque?
Relevant equations:
T=Ia
Tgrav=-mgx(cm)
