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. If the impactor has pushed a mass equal to its own mass at this speed, its whole momentum has been ...
The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity. [ 1 ] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the ...
The predicted impact point (PIP) is the location that a ballistic projectile (e.g. bomb, missile, bullet) is expected to strike if fired. The PIP is almost always actively determined by a targeting computer , which then projects a PIP marker (a " pipper ") onto a head-up display (HUD).
This is expressed in units of velocity (millimeters per microsecond, for example) and compares the relative flyer velocity produced by different explosive materials. For imploding systems, where a hollow explosive charge accelerates an inner mass towards the center, the calculations additionally take into account:
The most common of these bullets are made of small diameter lead pellets, placed in a thin copper shell, and held in place by an epoxy or similar binding agent. On impact, the epoxy shatters, and the copper shell opens up, the individual lead balls then spread out in a wide pattern, and due to their low mass-to-surface area ratio, stop very ...
The flail space model (FSM) is a model of how a car passenger moves in a vehicle that collides with a roadside feature such as a guardrail or a crash cushion.Its principal purpose is to assess the potential risk of harm to the hypothetical occupant as he or she impacts the interior of the passenger compartment and, ultimately, the efficacy of an experimental roadside feature undergoing full ...

Impact parameter b and scattering angle θ In physics, the impact parameter b is defined as the perpendicular distance between the path of a projectile and the center of a potential field U(r) created by an object that the projectile is approaching (see diagram).
