2) TECHNICAL EXAMINATION – refers to the examiners who examine bullets and/or shells whether fired from also whether or not cartridges were loaded and ejected made by the suspected firearm submitted. It includes the study of the class characteristics of firearms and bullets. It concerns mostly with the collection, marking, preservation, packing and transmission of firearms evidences.

This is the real branch of the science which the police use as their guide in field investigations. Is one branch of ballistics which refers to the investigation and identification of firearms by means of ammunition fired through them. 3) TERMINAL BALLISTICS – treats of the effects of the projectiles on the impact of the target. 2) EXTERIOR BALLISTICS –treats of the motion of projectiles after leaving the muzzle namely trajectory, velocity, range, penetration, etc. BRANCHES OF BALLISTICSġ) INTERIOR BALLISTICS – treats of the motion of projectiles while still in the firearm namely the study of combustion of powder, pressure developed and velocity. It is the science dealing with the motion of projectiles and the conditions governing that motion or the study of natural laws relating to the performance of gunpowder and projectiles in firearms. Science refers to the systematized body of knowledge Motion refers to the movement of projectile from the firearm to the target and Projectiles refers to metallic or non-metallic objects propelled from a firearm. BALLISTICS Is the science of motion (travel) of a projectile in flight. Subsequently it was universally practiced & accepted as manifested in the different court dockets throughout the world. Goddard pioneered the introduction of this science in the Northwestern University, Chicago, U.S.A. Ballistics dates back during the days even before the famous French artist Leonardo da Vince (1500 A.D.) as can be gleaned in his sketch of Steam-powered cannon through the hand cannons and primitive muskets like the matchlock, wheel-lock and flintlock firearms. From those words the term Ballistics was derived to indicate the science of moving projectile. The word " Ballistics" originated from the Greek word "Ballein" or "Ballo" which means “to throw" and from a Roman war machine called "Ballista" - a gigantic bow or catapult used to throw missiles and large objects such as stones at a particular distance to deter animals or enemy forces.
