The very high strength of the magnetic field may cause projectile effect (or "missile-effect") accidents, where ferromagnetic objects are attracted to the center of the magnet. Pennsylvania reported 27 cases of objects becoming projectiles in the MRI environment between 2004 and 2008. [20] There have been incidents of injury and death.
A ricochet (/ ˈ r ɪ k ə ʃ eɪ / RIK-ə-shay; French:) is a rebound, bounce, or skip off a surface, particularly in the case of a projectile. Most ricochets are caused by accident and while the force of the deflection decelerates the projectile, it can still be energetic and almost as dangerous as before the deflection.
The projectile carried 88 M42/M46 grenade-like dual purpose submunitions. The grenades are very similar, but M42 side wall is optimized for fragmentation characteristics while M46s have thicker walls strengthened to withstand additional setback loads in the last three aft layers of the projectile, where they are placed.
A sling is a projectile weapon typically used to throw a blunt projectile such as a stone, clay or lead "sling-bullet". A sling has a small cradle or pouch in the middle of two lengths of cord. The sling stone is placed in the pouch. The middle finger or thumb is placed through a loop on the end of one cord, and a tab at the end of the other ...
However, when the projectile exits the barrel, this functional seal is removed and the highly energetic bore gases are suddenly free to exit the muzzle and rapidly expand in the form of a supersonic shockwave (which can often be fast enough to momentarily overtake the projectile and affect its flight dynamics), thus creating the muzzle blast.
In projectile motion the most important force applied to the ‘projectile’ is the propelling force, in this case the propelling forces are the muscles that act upon the ball to make it move, and the stronger the force applied, the more propelling force, which means the projectile (the ball) will travel farther. See pitching, bowling.
A kinetic energy weapon (also known as kinetic weapon, kinetic energy warhead, kinetic warhead, kinetic projectile, kinetic kill vehicle) is a projectile weapon based solely on a projectile's kinetic energy to inflict damage to a target, instead of using any explosive, incendiary/thermal, chemical or radiological payload.
The chemical toxicity of depleted uranium is identical to that of natural uranium and about a million times greater in vivo than DU's radiological hazard, [101] with the kidney considered to be the main target organ. [102] Health effects of DU are determined by factors such as the extent of exposure and whether it was internal or external.
