Refers to the projectile’s speed from the moment it leaves the gun’s muzzle until it drops to the ground. The velocity of the bullet is expressed in feet per second. The horizontal velocity of a projectile is constant. It means that the projectile’s velocity does not change the moment it exits the muzzle end of the gun until it reaches the maximum effective range. It is possible when the gun is pointed in a horizontal direction. On the other hand, a vertical acceleration will occur caused by gravity when the gun is directed upward. The vertical velocity of a projectile changes by 9.8 m/s each second.

A1. Refers to the velocity of the bullet as it strikes the target. The velocity of the bullet ceases or decreases the moment it hits the target because of the resistance of the objects of tissues in die person’s body. Aside from the quantity of ganpowder, terminal velocity will also vary depending on the hardness of the object hit, distance, and the design of the bullet. The motion of a pointed nose bullet will not immediately stop as it strikes the person’s body since lesser resistance from the tissues will be encountered. Moreover, it will create a straight trajectory except when it hits harder tissues and bones. If the target is situated at a close distance or within the effective range, the like hood that the bullet’s velocity will not stop and further create an exit wound regardless of its design

Refers to the depth of entry of the bullet upon hitting the target. The depth of penetration depends on the bullet’s velocity, design, weight, hardness, and distance of the target from the firearm. A pointed nose bullet that brings higher speed will create deeper penetration on the body of the person situated within the effective range. The depth of penetration can be determined by examining the extent of the permanent cavity on the wound of the victim. A permanent cavity refers to the hole left by the passage of the projectile that is proportional to the size of the projectile. That is the volume of space once occupied by tissue that has been destroyed.

Refers to the energy carried by the projectile as it leaves the muzzle end of the firearm. The amount of energy depends on the load and quality of the gunpowder. The bullet that is still in the gun chamber already brings massive energy. Therefore, it is also fatal even if the bullet has just exited from the muzzle end of the fireann.

26. This branch of ballisties is also known as intermediate ballisties. It focuses on the projectile's behavior from the moment it exits the muzzle of the gun until the pressure behind the projectile is equalized. The heated gas produced in the gun chamber brings a massive pressure until it reaches the muzzle end. The gases are free to go beyond the bullet and expand in all directions as it exits the barrel. This phenomenon will create a flash and massive noise beyond the gun's muzzle Transitional Ballistics 8. Muzzle Blast C. Muzzle Flash D. Flash Suppressors

This force serves as the source of the energy of the bullet. Therefore, the bullet is already fatal while still inside the firearm because the pressure brought by the heated gas inside the chamber had already been tremendous. The knocking power of the bullet depends on the quantity of gunpowder because this is where the pressure and force are ultimately coming from.

4. The bullet is a little bit bigger than the diameter of the firearm's bore. So that it can pass through the bore, its cylindrical surface will be engraved by the rifling of the gun. This process produces a significant marking on the bullet called the rifling mark. Moreover, this engraving caused the small particles from the buller's body to be accumulated inside the barrel. It is called metal fouling. If this accumulation of residue or particles will not be cleaned or removed, it will cause rust and further result in erosion in the gun barrel. Erosion in the gun barrel will produce new significant characteristics of the rifling. AEngraving Of The Cylindrical Surface Of C Barrel Leading The Bullet B. Cylindrical Surface D. Erosion

4. The heated gas produced in the cartridge will expand. Both the vapor pressure and the volume it occupies will increase. However, this is enclosed in a sealed and a small container which is too small to accommodate its expansion. As such, more impacts on the walls of the container and an increase in the pressure will be developed. The weakest part of the cartridge against the massive pressure of the heated gas inside is the mouth where the bullet is crimped. Thus, the forward movement brought by the pressure of the heated gas caused the bullet to be propelled towards the bore. As a result of the backward direction of the heated gas, the cartridge case is extracted from the chamber and pushed towards the breech face of the firearm. The contact between the breech face and the base of the cartridge case will produce breech face marking A Chamber B. Chamber Markings Pressure Develop D. Pound Per Square Inch

First is major recoil, which refers to the equal and opposite reaction of the gun that occurs immediately after the beated gas exits from the barrel of the firearm and comes in contact with the atmosphere. This results in the whole gun moving backward. Another is a minor recoil. It refers to the equal and backward movement of the pistol slide after the cartridge case is pushed by the heated gas out from the chamber. This process resulted from the collision between the base of the cartridge case and the breech face. The breech face is an integral part of the bolt. The bolt is attached to the slide.

89. Refers to the energy brought by the projectiles upon hitting the target. The design and weight of the bullet and its velocity, play a vital role on how the kinetic energy is transferred to the target. The level of energy brought by the bullet can be determined by examining the extent of the temporary cavity on the victim's wound. A flat nose or dumdum bullet projected by a high power firearm will produce a wider temporary cavity on the target. A temporary cavity is also known as a stretch cavity. That is because it acts to stretch the permanent cavity, increasing the wounding potential. The potential for wounding via a temporary cavity.depends on the elasticity of the tissue, buller fragmentation, and the rate of energy transfer. A. Back Curve B.

85. Refers to the path formed by the projectile during its flight or motion. A wobbling pattern on The projectile's trajectory will usually occur within five to ten meters from the firearm's muzzle This motion happens since the projectile that exits from the muzzle of a rifled bore firearm is not immediately stabilized. This time, the bullet is still vulnerable to the impact of air resistance. It can only recover the moment the projectile reaches beyond this five to ten meters from the firearm's muzzle since the stability in this distance is already completed. Additionally, the projectile will form another shaking pattern beyond the effective range as it gradually loses its stability and velocity. Trajectory B Air Resistance C. Yaw D. Range
