"Nettetw h e r e I [k g m 2] = m · r 2. It can be derived from the formula that the torque depends on the moment of inertia and hence on the distribution of the mass of the object and its distance to the centre of rotation. The angular acceleration is proportional to the magnitude of torque.. The moment of inertia is the rotational equivalent of force about an axis in … " - Holding torque equation
