Yah your right. My bad. Been a long time. Even though, don't know how the hell I kittened that up.

It truly is an amazing scene though:

The full scene:

A little on the racist side, although I don't think that Clarence's dad was a racist, and that the only reason he said what he did was out of spite and to avoid torture.

So unless physics works different in Iceland....

So they are 80 GJ railguns
that is 80,000,000,000 J

Work equals change in energy

80,000,000,000= 1/2 M V^2

assuming the mass of railgun projectile is 100 kg (prolly on the heavy side)

V= 28,284 M/S

Like many things in Dust 514 they are so advanced they have gone all the way around the other side and become antiquated versions of themselves.

There are an awful lot of assumptions here, most importantly that gravity and atmospheric density on Dust planets are the same as Earth's. 16GN is not a measurement that would exist anywhere other than our own planet.

Unless I missed something Pent'noir was referencing the energy (work) for change in position, not gravitational force.

But yeah it would be pretty elaborate to have a muzzle drop discussion for different planet densities. Different averaged gravities near a planetary surface would also change movement rates on clones, vehicles, don't want to even contemplate the effects on Dropships.

So they are 80 GJ railguns
that is 80,000,000,000 J

Work equals change in energy

Also air composition at that point. Not every habitable planet is going to have the same concentrations of gases. And what about inhospitable ones? How will all those gases effect a weapon? What is the atmospheric pressure of those worlds? Higher or lower wind speeds? Moisture content? All of that could effect how any weapon performs. It would be hilariously terrible if they included that much detail.

Quick this is a high pressure/gravity world got to change to lighter ammo and a heavy suit to be able to even move!

Well, if you want to get all technical....

-Why does the MCC just spontaneously explode when its health runs out? Shouldn't it slowly deteriorate and then fall to pieces? But nope, it looks perfectly fine until the last shot then it auto-detonates.

-Why do I die when my armor runs out? What if I'm being shot in the leg? Since when has anyone died instantly from a bullet to the leg?

-Why do handheld forge guns do more than the massive railguns on tanks?

-Why are we only allowed to use better technology when we receive imaginary SP points?

-Why does losing a battle award you the same things as winning?

-etc. etc. etc.

Funny I know.

We must be on the same page. Including drag (from gasses) had occurred to me. For weapons it's generally insignificant unless said object is moving a ridiculous velocity (*cough* railguns *cough*) or said gas is particularly dense (gas giants at certain altitudes).

In total agreement with you Fraceska that too much science can be a bad thing. My opinion is too little isn't any better. Half the fun (and headache) is finding the balance.

Am i the only one lost in this thread? Sorry, Physics was a class I cheated and BS'd my way through in high school and college.

I now make 6.75$ an hour at McDonalds.

Seems to me you're assuming 100% efficient conversion of electrical energy into kinetic. Rarely does that happen.

So unless physics works different in Iceland....

So they are 80 GJ railguns
that is 80,000,000,000 J

Work equals change in energy

80,000,000,000= 1/2 M V^2

assuming the mass of railgun projectile is 100 kg (prolly on the heavy side)

V= 28,284 M/S

Now that makes it from my house in Wisconsin to Iceland roughly 3 min.

That would be enough to orbit almost ANY planet
That hits the 600 m max range in .02 seconds.
If you had a 30 FPS film of the railgun you would not even catch the projectile in 1 frame

The air pressure would be enough to blow clones away

Now lets assume the shield tank weighs about 100 Metric tons
(M1 abrams tank weighs 60 Metric Tons)

Then M1V1= (M1+M2) V2

V2 = v tank
V2 = 31 M/S

That is more than the top speed of the tank, so if it is moving at full speed it will be pushed back at about 10 m/s

So CCP are they really 80GJ railguns?

Even assuming something insane, like a 50% railgun inefficency, just half all the speeds and double the times and it is still outrageous. I lol so bad when i was doing this!

So ya, this is what I do when I don't play Dust

Good thread VicBoss. Plus one.

Not to be a wet blanket here but is that 80GJ the energy put into the projectile or the energy used in the system to then move said projectile. If the later the amount would be less than 80 GJ. Probably significantly so.

Obviously the only way to be sure is for us all to get together with a railgun and experiment. That and rig a grill above the wire coils so we can grill up some Mongolian barbecue.

Commonsense would indicate that the 80GJ's refers to the projectile energy because otherwise it wouldn't actually tell you anything about the system.
