Abstract
"Why does not a spinning top collapse?" is a puzzling question. Standard solution using angular momentum and torque is not intuitive enough. Thus intuitive explanations for the question have been proposed. We provide scaffolding for an intuitive explanation for the question. Accelerated point-masses in the top exert forces on the frame, which balances the effect due to gravity. The explanation is supplemented by the two following points. A more rigorous conceptual framework of the explanation is provided. A full calculation of trajectory is given. Nutation of spinning top is a difficult issue to understand physically. However, the nutation can also be understood by the intuitive explanation. We discuss another intuitive explanation.
