喺某啲情況下expected value會關事
... Thus, for the case of a quantum harmonic oscillator, the expected position and expected momentum do exactly follow the classical trajectories.
至於你話show丁jer本質上點同newton second law關事，可能佢講緊呢樣野?
https://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation
Solving this equation gives the position and the momentum of the physical system as a function of the external force {\displaystyle \mathbf {F} }\mathbf {F} on the system. Those two parameters are sufficient to describe its state at each time instant. In quantum mechanics, the analogue of Newton's law is Schrödinger's equation.
利申：冇認真學過qm
