"Striations" are tiny microscopic scratches found on the surface of a bullet caused by the rifling in a firearm barrel. These markings are unique to each firearm and can be used in forensic investigations to match a bullet to a specific gun.
Yes, that is correct. Friction is indeed the force that resists the relative motion or attempt at motion of two surfaces in contact with each other. It arises due to the interactions at the microscopic level between the atoms and molecules of the two surfaces.
Value refers to the relative lightness or darkness of surfaces. In art and design, value is used to create contrast, depth, and dimension in images.
Yaw refers to the rotation or deviation of a bullet's long axis from its original flight path. This can occur when a bullet destabilizes in flight, causing it to lose accuracy and potentially tumble upon impact. Yaw affects a bullet's stability and terminal ballistics.
The noun 'bullet' is a singular, common, concrete noun; a word for a thing.
Bullet ballistics refers to the behavior of a bullet in flight, including factors such as velocity, trajectory, and accuracy. It involves studying the impact of various variables like distance, wind speed, and bullet design on the bullet's performance upon firing. Understanding bullet ballistics is essential for precision shooting and hunting.

Grain refers to the weight of the bullet when measured on a powder scale.

Gross pathology refers to what can be seen with the naked eye, and microscopic pathology uses a microscope.
The term "762" refers to a 7.62mm bullet. This is a common size for European guns and the AK-47. The 54 refers to the length of the round or the powder, I forget. Not sure exactly what bullet this describes but that is the diameter size (caliber) of the bullet.
If you're referring to a cartridge for a handgun or rifle, there are only 4 parts. The case, the primer, the powder charge and the bullet. "Bullet" actually refers only to the piece of lead.
No, histology is a common noun. It refers to the study of the microscopic structure of tissues.
true

Ammunition refers to a complete cartridge consisting of a primer, case, powder charge and bullet. Bullets refers to the actual bullet component, or the projectile itself. I buy bullets to reload ammunition.
FROM NGC: refers to either the smoothing of a coin's fields to remove scratches, corrosion and other forms of damage or to the restoration of lost details through use of a graver or knife. When a single side of the coin is affected, the terms OBV TOOLED and REV TOOLED are used.
