Biomechanics involves the field of study that applies the laws of physics and engineering principles to analyse the motion of occupants or pedestrians and the forces which act upon them during a motor vehicle accident. Biomechanic assessments may encompass the following:

Determination of Seatbelt & Helmet Use Assessment of Restraint Effectiveness Analysis of Occupant Trajectory/Ejection Analysis of Impact Forces on Occupants Crash & Injury Data Analysis
	Analysis of Impacts to Pedestrians Low Speed Impact Analysis Anthropometric Studies Exemplar/Surrogate Studies Determination of “Who Was Driving?”
