Teaching physics using programming of simulations

It has long been agreed that the best physics teaching is by observing the experiment. But in some cases, experiments are not feasible for different reasons (time of the experiment is too short or too long to observe, experiment can be dangerous or extremely expensive). For counted reasons we use simulations which are computer programs that simulate real environment with various degree of reality. Simulations are used to hide the underground complex physics from the less skilled physics students who can observe and analyse the natural phenomena even without knowing all physics background. But we wanted to try something else – teach physics through gradual building of more and more complex simulation – hence teaching physics through programming. In our article we are going to present the scenario how to use such approach, and the analysis of two programming languages Python and Visual Basic to see which is more appropriate for developing visual simulations for students.
