Why Does A Hollow Sphere Have More Rotational Kinetic Energy?

Why Does A Hollow Sphere Have More Rotational Kinetic Energy? Therefore, the rotational kinetic energy will depend on the moment of inertia. But the answer says that since the hollow cylinder has greater moment of inertia, it has greater rotational kinetic energy. Why do hollow objects have more rotational inertia? (Although they have the same

What Type Of Forces Allow An Object To Stay At Rest Or At A Constant Velocity?

What Type Of Forces Allow An Object To Stay At Rest Or At A Constant Velocity? Inertia is a force. Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. What
