A doubt in the rotational analogue of F=ma

[QUOTE="kuruman, post: 6432184, member: 192687"] In short, as long as you write ##\tau=I~\alpha##, with the torque ##\tau## and the moment of inertia ##I## of the rigid body expressed about the [B]same[/B] reference point, Newton's 2nd law for rotation will be valid and ##\alpha## will be about the same point. This post is a repeat of what [USER=85613]@A.T.[/USER] said except that the importance of matching torque and moment of inertia reference points was not spelled out in post #2. [/QUOTE]
