"When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body."

For a nerdpoint, what is this and how is it applied to this week`s comic? ^-^

I love this kind of stripes... so easy to translate... XDDD

here, we have 3rd Newton law, and he fired his railgun behind the suit to use the recoil as extra propulsion :)

Which probably ain't to much compared to a chemichally powered projectile of similar kinetic energy. I doubt it could shoot a weightclass 8 or 9 suit backwards. How would the HRR suits handle that then?

I'm more curious as to what kind of force the slug exhibits on chitin-armored aliens. You could then calculate how many spacebugs you can efficiently turn into space-goo. Welcome to the blender. Softdrink of the day - "Biomass 9000" containing all the energy you need to create 9001 chibinids.

Know your physics
Railsguns have a thousand times higher maximum knetic energy, because they are not limited by the Speed of Sound in the explodign Gas. They are only limited by how much energy you can pump into it. Wich is why we research rail/gaus guns as the Future weaponsystems. (en.wikipedia.org/wiki/Railgun).
Also do not forget that so far they only fired or even aimed the gun while standing, never flying. Because it has an insane recoil to reach kilometer long ranges.

recoil plus
besides, when firing the railgun the jetpack could compensate for the recoil. in this instance it adds to the recoil.

the way to launch a projectile (chemical or railgun) is almost not taken into account for recoil. (it's even a bit worse for chemical, as some of the propulsive energy is lost as heat)

basically, your kinetic energy will be mass * speed^2, this kinetic energy being imparted on both the launcher system and the projectile. (of course, as the projectile has much less weight than the launcher, the speed the projectile gains is much more important in comparison to the recoil suffered)

nevertheless, we don't use railguns for the moment because we principally need to devellop a good enough power source to power it.

That doesn't look like a railgun
It looks more like a proyected energy weapon, like a huge laser cannon. Otherwise he wouldn't been able to completely vaporize that Durchii bitch. If that is the case, it should have almost no recoil, as the mass of light is close to zero.

what...? who...
who's holding the gun? the spehhs mehreen, the kroott, or the suit? the picture just generates a heap of questions.

Type of weapon
@JuankiMan, unless, of course, it's an ion accelerator.

The mass of that many ions, at that speed, would generate recoil.

Reading all this...
about Railguns....MY BRAIN HURTS!!!! NURSE!!!

Railgun Issues
Actually it's not the issue of powering a railgun that makes them hard to use, we have easy access to nuclear reactors. The issue is since unlike Gauss Guns the slug in a railgun is touching the rails after about the third shot the riles are pretty much destroyed.

So until we make an alloy of some kind that can survive launching projectiles at that speed while still being conductive it's impractical to use one.

Railguns : for infantry sized weapons, power source is gonna be a problem :) - i think that's why they do not make a lot of research in the other areas of the gun itself.

today, we have lots and lots of interesting technologies, main problem is to have a sufficiently small and efficient power source for it :)

Infantery Railgun
Actually beside the energy source, infantery weapons are limited by the recoil. A vehicle (even a mech) can be build sturdier and stronger. The average human cannot.

But otherwise yes, finding a suiteably small and effective powersource is a big problem. Aside from finding materials that can take that much energy.

About varporizing the durchii: Do you have any idea just HOW much kinetic and heat energy a railgunprojectile can produce? It's enough to varporize a human sized body. A million times over.

@someone with glasses: Kroot do not use ranged weapons. Johnsone never had one in his Armor and has lost said armor. While the suit has been using a giant blue gun since it was first shown.

@Christopher
No offence, but unless they changed it in the latest codex, kroot can use guns. Not many kroot gunners are seen on the tables because the tau are usually better with long range weapons. But tau are bad in close combat, something that the kroot are expert in, so they are used as blocker or meatshield. This explain why almost all the kroot auxiliaries are close combat oriented.
