What is Kinematics?
Kinematics comes from the Greek word “kuma” or “kumat”, which means movement. It is the study of movement without regard to the forces or masses involved. Trauma is all about movement as all trauma, whether it be blunt or penetration trauma, involves the phenomenon of movement.
All injury relates to movement and its relationship to the body. The source of the movement may be as commonplace as a motor vehicle or a penetrating foreign body. It can also be as esoteric as the moving particles found in heat injuries, blast injuries, or ionizing radiation. Kinematics is all about velocity and acceleration. When a car accelerates and strikes a pedestrian, the trauma received is all about kinematics.
