There are no meaningful potentials in the one-particle universe that the OP described. However the particle is "really moving," you could just invent a coordinate system to make it "move" however you like.
Even introducing EM would bump you up to at least two particles! The only reasonable one particle universe would be one where the partice was coupled to nothing.
(It is under the "try to interpret it as they meant it" doctrine that I go from a proton to a particle that doesn't leave behind a disturbed field when it accelerates.)
