Inertia tensor for a sphere?
Could someone help explain how I get the intertia tensor for a sphere and how would I apply that to the calculated torque and angularVelocity of a sphere?
And is the inertia tensor only for rotations and not for linearvelocity?
thx

Linear velocity is related to linear momentum (and force is related to linear acceleration) by the total mass of the object, while the inertia tensor plays a similar role with respect to angular effects.
