## Step 1<br />The first term, "Abrasion mark", refers to a mark that is left on a surface due to friction or scraping. This term is often used in the context of ballistics to describe the marks left on a bullet or a target due to the bullet's movement.<br /><br />## Step 2<br />The second term, "Ballistics", is a branch of physics that studies the motion of projectiles. In the context of firearms, ballistics refers to the study of the behavior of bullets, including their trajectory, velocity, and impact.<br /><br />## Step 3<br />The third term, "Barrel", is a long, metal tube that is part of a gun. The barrel is where the bullet is fired from.<br /><br />## Step 4<br />The fourth term, "Bore", refers to the interior of a gun barrel. It is the space where the bullet travels through.<br /><br />## Step 5<br />The fifth term, "Breech/Breechblock", is the part of a gun where the bullet is loaded. It is the rear part of the barrel.<br /><br />## Step 6<br />The sixth term, "Bullet", is a projectile that is fired from a gun. It is the object that is shot out of the barrel.<br /><br />## Step 7<br />The seventh term, "Caliber", refers to the diameter of the bullet or the bore of the gun. It is a measure of the size of the bullet and the gun's barrel.<br /><br />## Step 8<br />The eighth term, "Cutting mark", is a mark that is left on a surface due to a sharp object. In the context of ballistics, it could refer to the marks left on a bullet or a target due to the bullet's movement.
