How to show that interaction potential depends only on separation of particles in system with position translation symmetry?
System
2 particles with mass moving in one spatial dimension $x$. Positions of particles are $x_1$ and $x_2$ respectively and they are only acted on by a conservative interaction force corresponding ...
