This is a further discussion of my hypothesis pertaining to explaining the ratio of redistribution of kinetic energy at elastic collision. It is my attempt to create an generic theory explaining related phenomena from collision, friction and thermal property. The key to united them is the internal structure of this object.
As we sliding an object through the ground, we are all familiar that part of the kinetic energy has become heat through friction. How? According to my modified wheel hypothesis, the mismatch of frequency or direction of vibration is the reason why orderly kinetic energy has become disorderly heat energy. The term heat energy may simply meant all the vibration energy that is not useful for the objective of moving the object. In mechanical term, it just meant the vibration does not match the direction of intended movement. Suppose we move an object forward then sidewards, all the forward energy has thus become heat. And in the case of sliding, it is the vibration of atom on the ground matching those of the moving object that cause friction (unintended transfer of kinetic energy from an object to the contacting surface), which has NOTHING to do with the shape of surface. As the case of collision, those who are vibrating orthogonal to the impending object are least able to absorb the kinetic energy of that object, and those who are vibrating in the same direction would be able to absorb most of that kinetic energy. It is yet another case of match and mismatch.
For transmission of thermal energy, I hypothesize there are different region of thermal transimittability in each object. Much like a Magnetic domain, the physical structure of the object has constraint the vibration or movement of that particular area so it exhibit regularity in thermal energy transmission (like the ratio of energy distribute on x,y,z axis). These regions are fixed for the case of rigid body. In order for heat energy to pass through one atom to another, it would require they are matching in the characteristic of vibration(like direction and frequency) to maximize the efficient of kinetic energy transfer. There are region that is likely to be hotter than other by the virtue of internal structure, while other to be colder.
Since the internal structure of object is assume to be fixed and invariant, therefore, whatever the form of transmission of kinetic energy it take: Collision, friction and thermal energy re-distribution, the kinetic energy has essentially pass through the identical structure and through identical mechanism to reach from one end to another. I would therefore suggest a link between all of them: The place that is colder is likely to be smoother, and would be more likely to gain kinetic energy from collision.
