Análise física em locais de mortes violentas

Abstract

Forensic science is an auxiliary branch of the Criminal Justice system, seeking to elucidate issues pertinent to the context of the crime, such as perpetrators, motives, and circumstances, thus contributing to the demonstration of the true truth within the already established criminal process. Thus, physical analysis at the scene of violent deaths is a field of study that aims to investigate and understand the circumstances and physical details of dramatic events. This analysis involves a series of technical and scientific procedures to collect and preserve evidence, which is precisely where physics comes in. Therefore, it is considered the primary area of application in forensic science. One of the branches of physics used in forensic analysis is mechanics, which encompasses both kinematics and dynamics and can be applied, for example, to determine the trajectory of a freely falling object, the direction and velocity of a projectile, or even the force of an object's impact. Thus, this research is justified by the need to demonstrate how physical concepts are of paramount importance in the field of forensic science and how these concepts are used to determine the dynamics of a given event. In some circumstances, traffic accidents and homicides can be analyzed from the perspective of the laws of physics. Therefore, four examples will be demonstrated of how physics is used in criminal forensics, to obtain an accurate conclusion. This work aims to demonstrate the importance of applying the laws of physics to scenes of violent deaths resulting from crime or accident, using specific forensic science methodologies. Therefore, we hope to demonstrate how the laws of physics are applied in forensic science and how important they are for understanding and establishing the circumstances surrounding these events, contributing to a criminal investigation.
