• It allows correct prediction of rotational effects in three dimensions

• The disk has larger I
• They are equal
• The hoop has zero I
• The hoop has a larger moment of inertia

• It eliminates gravity
• It stops all motion
• It makes objects massless
• It separates translational and rotational motion

• It moves with the heavier part
