    The physicist Sir Isaac Newton first developed this idea to get rough approximations for the impact depth for projectiles traveling at high velocities. Newton's approximation for the impact depth for projectiles at high velocities is based only on momentum considerations. Nothing is said about where the impactor's kinetic energy goes, nor what happens to the momentum after the projectile is stopped. The basic idea is simple: The impactor carries a given momentum. To stop the impactor, this momentum must be transferred onto another mass. Since the impactor's velocity is so high that cohesion within the target material can be neglected, the momentum can only be transferred to the material mass directly in front of the impactor, which will be pushed at the impactor's speed.

    Terminal ballistics - Wikipedia

    Terminal ballistics also known as wound ballistics is a sub-field of ballistics and refers to the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design as well as the velocity of impact largely determine the effectiveness of penetration. The concept of terminal ballistics can be applied to any projectile striking a target. Much of the topic specifically regards the effects of small arms fire striking live targets, and a projectiles ability to incapacitate or eliminate a target.

    Penetration (firestop)

    This page is obsolete. A projectile that enters the ship can encounter up to four or five layers of armor and may stop or ricochet at each layer. In this regard the developers attempted to adhere to historical realism and simulate all significant layers of armor.

    In mechanics , an impact is a high force or shock applied over a short time period when two or more bodies collide. Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period. The effect depends critically on the relative velocity of the bodies to one another. At normal speeds, during a perfectly inelastic collision , an object struck by a projectile will deform, and this deformation will absorb most or all of the force of the collision. Viewed from a conservation of energy perspective, the kinetic energy of the projectile is changed into heat and sound energy, as a result of the deformations and vibrations induced in the struck object.
