Penetration refers to the ability of an object or substance to pass through another material or barrier. It’s often used in the context of projectiles or fluids penetrating surfaces. Perforation, on the other hand, specifically denotes the creation of holes or openings in a material, often as a result of penetration. Both terms relate to the interaction between objects and materials.

FAQs
What is the formula for armor penetration? Armor penetration is calculated based on the specific ammunition and weapon used, but a simplified formula for estimating armor penetration is: Penetration = (Projectile Kinetic Energy) / (Armor Thickness). This formula considers the kinetic energy of the projectile and compares it to the thickness of the armor being penetrated.
