According to Wikipedia (yeah I know but it’s not the only place that said this is the meaning) Ballistics is the science of mechanics that deals with the flight, behaviour, and effects of projectiles, especially bullets, gravity bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
When I think ballistics I always thought it was studying the bullets fired from a gun to see if the rifling matched with a known sample, either one in a database or one found at the scene of a crime. I found out there is more than one ballistics category. There is internal ballistics (which is within the gun), external ballistics (which is from the gun to the target), terminal ballistics (when the projectile hits the target). I found an amazing explanation of the various types complete with diagrams here. It’s part of a firearms tutorial from The Internet Pathology Laboratory for Medical Education.
In Canada the RCMP has an Integrated Ballistics Identification Network (CIBIN). The network allows police to have their ballistics evidence compared against any evidence from across the country. Plus it can also be compared against the U.S. National Integrated Ballistics Information Network.
