Let,s suppose we have a particle moving under a potential V:(adsbygoogle = window.adsbygoogle || []).push({});

By Heisenberg picture we know that:

[tex]\frac{dx}{dt}=p/m [/tex]

so if we knew x(t) and x(t+h) we could calculate the expresion:

[tex]x(t+\epsilon)-x(t)=p\epsilon/m [/tex]

so knowing x(t) and x(t+e) we could calculate the momentum of the particle:
