The present work allows to intuit the unlimited scope of the application of physics in the forensic field, to introduce in the analysis of the investigation of a road accident, computerized simulation techniques that are derived from a rigorous study of the specific accident, to obtain details specific regarding the physical parameters of the vehicle and the pedestrian involved in the accident such as: speed, acceleration, kinetic energy and displacement. The reconstruction of the vehicle-pedestrian accident, for the frontal case, requires a detailed analysis of all the parameters that have an impact on the event, this analysis is shown through a virtual simulation carried out in solidwork 2014 where these simulations do not replace physical crash tests, but it more accurately evaluates the dynamics of the vehicle and that of the pedestrian with respect to their center of mass. Through this tool, graphs are analyzed in time corresponding to speed, acceleration, displacement and kinetic energy that allows to confront the damage to the vehicle and the injuries to the pedestrian with their dynamic behavior, in addition the virtual simulation allows to deepen in the degree of deformity of the structure of the car and how it affects the appearance of injuries in pedestrians, they are also the only practical option to test the large set of behavioral safety assessments that are needed.
