Some Hamiltonian situations

To clarify the models simulated, we first present them as noise-free Hamiltonian systems. These simulations make it possible to see the relative masses of the particles, and the nature of the potential.

First we show a driver and piston both having identical mass m=1. The piston is subjected to a constant force to the left, so its trajectory, in the abscence of collisions, is a parabola. Notice, when the driver and piston collide, that they exchange horizontal velocities, as is standard for identical-mass Newtonian particles.
