Linear Momentum and Vector Sum Analysis Made Simple
Linear Momentum and Vector Sum Analysis
by Wiley L. Howell
Wiley Howell knows the importance of keeping linear momentum equations simple for a jury. He wrote this book to help you make linear momentum equations simple and to introduce you to a less time consuming way to do vector analysis as a check on the accuracy of the answers obtained from using those equations.
He starts with the general Linear Momentum Equation and, using the 360-degree method of angle measurement, shows how it can be modified to give you the equations needed to determine the impact speeds of vehicles in any kind of collision: head-on, rear-end, right angle and acute angle. He also provides a handy vector-diagram check on the accuracy of your speed calculations.

- Angle Collision with Multiple Departing Sections
- In-line Collisions
- Vector Sum Analysis
This book is recommended to anyone who must testify in a court case where speed has been determined by linear momentum.
