Accurate vehicle accident reconstruction requires the application of established engineering and physics principles initially developed by the English philosopher, scientist, and mathematician, Sir Isaac Newton (1643-1727), originally published in his “Philosophae Naturalis Principia Mathmatica” (the “Principia”). Analysis of all forces is dependent on Newton’s 3 “Principles of Motion.” The Accident Expert’s technical experts are formally trained in the application of these principles when analyzing vehicle accidents.
