This is a 40 hour (one week) technical training course for advanced collision investigators. The field of study is "Momentum Analysis in Motor Vehicle Collisions." The class is designed for the advanced technical investigator and/or ACTAR accredited Reconstructionist who wants to fully understand the principles of momentum without the use of situational formulas. Upon conclusion of the class the student should be able to derive momentum formulas based on the dynamics of the crash, understand and perform vector sum analysis, and have a better working knowledge of post-impact drag factors. Completion of this class should better prepare the student to investigate motor vehicle collisions and be successful in courtroom presentations.
