>What is vibration, other than movement of tiniest particles? Imagine a pendulum, moving back and forth. The average movement is zero! Even for different pendulums moving at different speeds. Vibration is a similar case. Obviously movement is not the most useful way to examine these systems, we want to look at other things too. Temperature is a measure of the kinetic energy involved. >maybe collision is what actually makes the temperature Kinetic energy is involved in both collisions and vibrations. >but for some insignificantly small chance, they do have no collisions for a few seconds We can compare to atomic fission, where the fission is also probabilistic - but the result is very predictable.
