A traffic collision represents a rapid biomechanical interaction between moving mechanical systems and their occupants. From a physical science perspective, the impact involves the transfer of kinetic energy, resulting in sudden deceleration forces that can exceed the structural tolerances of both the vehicle chassis and the human body. These forces induce various traumatic injuries, ranging from localized blunt force trauma and fractures to complex internal damage caused by whiplash or crush injuries. Medically, the study of these events involves analyzing the patterns of injury against principles of physics, requiring careful assessment of forces, momentum, and energy dissipation to understand the mechanisms of morbidity.
