homework and exercises - How to find constant of motion for Hamiltonian system?


I have to find a constant of motion associated to this Hamiltonian but I don't know how to proceed.


H=p022m+p122m+p222m2V(r1r0)+V(r2r1)


where V(x)=e2|x|.


I don't know what x is.


This Hamiltonian refers to a system of 3 particles (0,1,2) with mass m and charge e.


The coordinates are rαi and conjugate momenta pβj with α,β=0,1,2.


I have written all the information that I have.

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
