Abstract

The simplest dynamical system is the point particle characterized by its mass. Its state is specified by its position and momentum. The dynamical law is the description of how these quantities change in time. For a free particle, the momentum remains constant while the position increases in the direction of the momentum. The increase is directly proportional to the elapsed time and inversely proportional to the mass. When such a particle is subjected to a force, the momentum also changes proportional to the force. The instantaneous state may be represented as a point in phase space which moves along a trajectory. For complicated interactions, the trajectories may form an intricate pattern but they do not intersect, and the generic dynamical evolution may be viewed as a mapping of the phase space onto itself.
