3.  Ballistics and or Rifling is the science that deals with the
motion of projectiles such as bullets, shells, rockets, and
aerial bombs.
 It is important to police officers who investigate crimes
involving shootings in order to match the gun to the bullet.
 It is also important to artillerymen, naval gunnery officers,
and to engineers who design firearms, missiles, bombsights,
and fire-control systems.

4.  Interior Ballistics
 Exterior Ballistics
 Terminal Ballistics

5.  This is the marking that is left on the bullets or
projectile.
 All guns leave a unique spiral scratch or marking on
the bullet as it fires.
 Police use this as a way to link bullet casings to the gun
that fired it

6.  The exterior ballistics are any factors that will effect
the bullet while in flight
 Wind
 Gravity
 Air resistance
 Drift
 Even the temperature and air density play a factor
Specialized bullets are used to reduce these factors such
as different weights and sizes as well as groves put into
the bullet or the shape of the bullet

7.  The study of terminal ballistics is the study of how a
projectile behaves after it hits the target
 The studies of this are done to help defend against
enemy attacks, and to prove the efficiency of a weapon
 The most common test for this is the use of ballistic gel

8. This gel is specially formulated to simulate
human body density, this is used to test and
demonstrate how a persons body will react to a
Bullets impact, and how much damage a bullet will do to
a person’s body

9.  Using Ballistics in court can be used on both sides of
the argument
 The defense can use it to prove that the bullet fired was
not linked to a defendants gun
 It can also link the criminal to the crime and prove that
he/she was at the crime scene and fired the shot
Fingerprints on shell casings is the best way to link a
bullet person who fired it but it is not always accurate.
