  A model for Opinion Particles, based on Bayesian-inspired models of Opinion
Dynamics such as the CODA model is presented. By extending the discrete time
characteristic of those models to continuous time, a theory for the movement of
opinion particles is obtained, based only on inference ideas. This will allow
inertia to be obtained as a consequence of an extended CODA model. For the
general case, we will see that the likelihoods are associated with variables
such as velocity and acceleration of the particles. Newtonian forces are easily
defined and the relationship between a force and the equivalent likelihood
provided. The case of the harmonic oscillator is solved as an example, to
illustrate clearly the relationship between Opinion Particles and Mechanics.
Finally, possible paths to apply these results to General Relativity are
debated.
