Particle Motion Animations
      The links below are to animations made using PSM for motions of particles under forces.



The motion of a single particle in one dimension under the rule x' = cos x + cos t

The motion of five particles in one dimension under the rule x' = cos x + cos t

The motion of several particles in two dimension under the rule x' = -y(1-x-y) y' = x(1-x-y)

The motion of several particles in two dimension under the rule z' = x' + iy' = az^2 + bz + c

The motion of a particle on a two dimension slide under gravity (friction-free)

The motion of four particles on a tautochrone or brachistochrone under gravity (friction-free)
