Microcomputer simulation of real gases - part 1: Intermolecular forces and spatial structure

The authors describe some simple programs for the simulation of the molecular dynamics of two-dimensional systems with a Lennard-Jones interaction potential. The software has been prepared for introductory physics courses at high school and college level, but different kinds of accompanying guides are required for these two levels. They take as their starting point the study of a two-particle system, in order to analyse the trajectories and to show the effect of the interaction.
