No, no they don't.
Try the energy transmitted through electric current.

Tasers are a method of pain infliction, not much more. A clean one that leaves no evidence of usage.

Bullets can mean all ammunition. Duh.DraQ said:Mind you, that before getting all butthurt nomask started by complaining about bullets in Q4, which means he meant things like machine gun, which uses standard bullets. No pressure waves, no exotic energy crap, no nothing.
Hollywood depictions of firearm victims being thrown through several feet backwards are inaccurate, although not for the often-cited reason of conservation of energy. Although energy must be conserved, this does not mean that the kinetic energy of the bullet must be equal to the recoil energy of the gun: in fact, it is many times greater. For example, a bullet fired from an M16 rifle has approximately 1300 foot-pounds of kinetic energy as it leaves the muzzle, but the recoil energy of the gun is less than 5 foot-pounds. Despite this imbalance, energy is still conserved because the total energy in the system before firing (the chemical energy stored in the explosive) is equal to the total energy after firing (the kinetic energy of the recoiling firearm, plus the kinetic energy of the bullet and other ejecta, plus the heat energy from the explosion). In order to work out the distribution of kinetic energy between the firearm and the bullet, it is necessary to use the law of conservation of momentum in combination with the law of conservation of energy.
Thus, when a bullet strikes a target, it may have a kinetic energy in the hundreds or even thousands of foot-pounds, which in theory is enough to lift a person well off the ground. (A foot-pound is the energy required to lift a one-pound weight to a height one foot off the ground.) This energy, however, is largely spent in the deformation or shattering of the bullet (depending on bullet construction), damage to the target (depending on target construction), and heat dissipation. In other words, because the bullet strike on the target is an inelastic collision, a minority of the bullet energy is used to actually impart momentum to the target.
You don't actually know how conservation of momentum works, or how momentum is not affected by internal forces (i.e. any mechanism inside the gun).Paula Tormeson IV said:You don't actually know how recoil works in machine guns and assault rifles. Nice faking though.

Which is basically caused by conservation of momentum, whereas you keep flailing about like a chimp you are and posting wikipedia excerpts regarding recoil not being caused by conservation of energy.Paula Tormeson IV said:The subject is recoil.

You don't have a dimmest clue regarding what you're talking about, and try to mask it by copypasta of stuff you don't understand either, but instinctively feel might be relevant - a sub-sapient manboonery at its finest.
Light, fast bullets. A lot of kinetic energy, but little momentum.Paula Tormeson IV said:Explain (almost complete lack of) recoil in assault rifles.
This. a 5.56x45mm NATO round is ~4 grams. A typical human male, maybe ~70kg. Since you brace the gun in your shooting stance, little recoil.DraQ said:Light, fast bullets. A lot of kinetic energy, but little momentum.Paula Tormeson IV said:Explain (almost complete lack of) recoil in assault rifles.
