• Resumen

  • Description of trajectories has been dealt in quantitative terms by means of mathematical formulas. Human beings do not use formulas to describe the trajectories of objects in movement, for instance, for shooting or catching a ball. Common sense reasoning about the physical world has been commonly solved by qualitative models. However, no qualitative model about trajectories of objects in movement has been developed up to our knowledge. In this paper, a qualitative representation model about kinematic properties of a system consisted of several objects moving uniformly (constant speed) in a 2D space has been developed. This representation is based on a geometric description of the most relevant kinematical aspects through the relation between the trajectories of two moving objects.
