Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ultimately occurs.
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.
When vehicles collide, the damage increases with the relative velocity of the vehicles, the damage increasing as the square of the velocity since it is the impact kinetic energy (1/2 mv 2) which is the variable of importance. Much design effort is made to improve the impact resistance of cars so as to minimize user injury.
[citation needed] Tank fired HEAT projectiles are slowly being replaced for the attack of heavy armor by so-called "kinetic energy" penetrators. It is the most primitive (in-shape) projectiles that are hardest to defend against. A KE penetrator requires an enormous thickness of steel, or a complex armor array to protect against.
As would be expected, an accurate estimation of the kinetic energy loss by a projectile is always important in determining the ballistic waves. — Lee, Longoria, and Wilson The rigorous calculations of Lee et al. require knowing the drag coefficient and frontal area of the penetrating projectile at every instant of the penetration.
An Australian sculptor has created a model of what the human body would have to look like to survive a car crash-- and it's the stuff of nightmares.. The artist, Melbourne-based Patricia Piccinini ...
For example, in Denmark rifle ammunition used for hunting the largest types of game there such as red deer must have a kinetic energy E 100 (i.e.: at 100 m (110 yd) range) of at least 2,700 J (2,000 ft⋅lbf) and a bullet mass of at least 9 g (140 gr) or alternatively an E 100 of at least 2,000 J (1,500 ft⋅lbf) and a bullet mass of at least ...
The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target.
