Accident Reconstruction
Introduction
Mechanics, when applied to accident reconstructions, deals with the relationships between
forces, bodies, and motion. e forces are produced by a combination of the relative motion
of the vehicles, occupants, or systems. e method used to describe motion from a math-
ematical standpoint is called kinematics.
e motion of the particular body is dened as its continuous change in position rel-
ative to a coordinate system. For most applications in accident reconstruction, the pre-
ferred coordinate system is the Cartesian system. Some applications require cylindrical
or spherical coordinate systems. In any ...
