Abstract

All physical analysis, including accident reconstruction, is ultimately based on physical quantities. Since the measurement of physical quantities is never absolute, they are always subject to variation. The relationship between this variation and the end results of the analysis is known as sensitivity. If a small variation in a given quantity produces a large variation in results, the analysis is said to be highly sensitive to that quantity. On the other hand, when a large variation produces a small change in the results, the analysis is said to be insensitive to that particular quantity. This article explains the usefulness of computer spread sheet programs to accident reconstructionists, and includes a case study.
