SUMMARY
This discussion clarifies the relationship between torque and moment of inertia, emphasizing that they are distinct physical quantities. Torque is defined as the product of force and lever arm length, while moment of inertia is calculated as mass times the square of the distance from the axis of rotation. The conversation highlights that doubling the mass doubles the moment of inertia, whereas doubling the distance quadruples it. Additionally, it is established that a longer lever arm increases torque, but a greater moment of inertia requires more torque to achieve the same angular acceleration.
