CANNELURE
3
simply refers to the projectile's rate of speed per unit of time, which is usually measured in ft/sec. The two kinds of velocities studied in exterior ballistics are muzzle velocity and projectile velocity

11
deals with the destructive actions and effects of projectile at the end of its flight
TERMINAL BALLISTICS
12
the depth of bullet penetration on the target.
TERMINAL PENETRATION
13
An unstable projectile may yaw violently or tumble, while a super stable projectile may maintain a fixed attitude in space regardless of how the tangent to its trajectory turns
PROJECTILES STABILITY
14
speed of the projectile when it strikes the target.
TERMINAL VELOCITY
15
Stability of projectile motion can be compared with two other conditions called
INSTABILITY AND SUPER STABILITY
16
significantly affects the normal trajectory of projectiles. It refers to the lateral deviation of the bullet's trajectory from the vertical plane through the axis of the bore caused by the rotation of the projectile
DRIFT
17
were both greatly interested in the force called air resistance, usually called drag, which reduces the speed of a projectile
GALILEO AND NEWTON
18
Also known as intermediate ballistics, transitional ballistics is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized

are projectile's motion from the moment of firing until impact at the target can be analyzed scientifically in four distinct phases
INTERNAL, TRANSITIONAL, EXTERNAL AND TERMINAL
28
it motion can be compared with two other conditions called instability and super stability
PROJECTILES STABILITY
29
Once a projectile reaches the summit of its trajectory, it experiences a downward reaction due to its weight
GRAVITATIONAL PULL
30
means a path that becomes more and more curves as range increases and velocity drops off. The bullet actually starts to drop the moment it leaves the gun muzzle
PARABOLIC TRAJECTORY
31

is accompanied by heat. This heat generated near the muzzle causes flash, which in farge gun is accompanied by flames.
BLAST SHOCK WAVE

BARREL LENGTH
34
it is also called interior ballistics, involves the study on how to initiate the motion of projectiles inside the gun and how projectiles travel through the gun barrel

There are two principal factors that influence the trajectory of a short-range projectile. there are:
Gravitational pull Characteristic of air through which it passes
40
violent reaction expansion of compressed gases
MUZZLE BLAST
41
it refers to the curved path of projectile from the moment it leaves the gun muzzle until it hits the target.

The two common ways to alter the normal phenomena in transitional hallistics are at follows
SUPPRESSING THE BLAST, REDIRECTING RECOIL
43
also known as exterior ballistics, involves the study of projectile's behavior from the time it leaves the gun until it ends its flight. The main problem of exterior ballisticians is determining the trajectory of the projectiles.
