FAQs

Question: What is the moment of inertia?
Answer: The moment of inertia is a measure of an object's resistance to changes in its rotational motion, depending on the mass distribution relative to the axis of rotation.

Question: How is torque calculated?
Answer: Torque is calculated using the formula τ = r × F, where τ is torque, r is the distance from the pivot point to the point of force application, and F is the applied force.
