Abstract. We describe algorithms and tutor programs for simulation and visualization of the trajectory sets of a few-body system including a movement of the carrier rocket taking account of basic forces forming pathways. We consider typical examples of visualization of movement of a classical particle with variable mass in the field of a massive geoid. We also study dynamics of a semiclassical few-body model and trajectory sets of two negative charged particles in the field of a positive charged surface. The symbolic computation system MAPLE is applied to generate computer codes using numerical integrators for solving the Cauchy problem and to simplify visualization tasks.
