For questions about kinetic weapons, their uses, technology, and application. Kinetic weapons move a mass to speeds hostile to the target. That mass may be as small as an electron or as great as an asteroid, so long as the question is about the object accelerating the mass and not the mass itself.
Kinetic: relating to or resulting from motion.
A kinetic weapon is any technology that accelerates a mass to velocities harmful to the intended target. This may be a slingshot, a particle accelerator, an M1 carbine, a railgun, or a blowdart tube. The purpose of the weapon is to harm or kill using the kinetic energy of the accelerated mass and does not relate to secondary effects such as the temperature or radioactivity of the mass.
