1. Objects with low potential energy are relatively stable, and objects will definitely change towards a state with low potential energy. When the tumbler falls down, the tumbler will return to its original position because the base that concentrates most of the center of gravity is raised, resulting in an increase in potential energy.
2. From the perspective of lever principle, when the tumbler falls, the center of gravity is always at the end, no matter where the fulcrum is, the tumbler will still return to its original position due to the large moment on the base.
3. Also, the bottom is round, and the friction is small, which is convenient for the tumbler to return to its original position.
Physical structure:
The tumbler is a hollow shell and is very light in weight. The lower body is a solid hemisphere with a large weight. The center of gravity of the tumbler is within the hemisphere. There is a contact point between the lower hemisphere and the support surface, and when the hemisphere rolls on the support surface, the position of the contact point changes. A tumbler always stands on the support surface with one point of contact, it is always a monopod. The formation of the ability to resist interference and maintain balance can be seen from the force of the tumbler.
