Escape Velocity

This is where you can discuss your homework, family, just about anything, make strange sounds and otherwise discuss things which are really not related to the Lancer-series. Yes that means you can discuss other games.

Escape Velocity

I been checking the planets out on the officail FL site and was wondering if the "Escape Velocity" listed for each planet has any thing to do with how you are affected by the mass of a planet, ether gravitational pull or taking off from a planet? Or is it just for general interest information only. I am assuming taking off from a planet is done automatically as in Privateer?

Post Wed Feb 12, 2003 8:22 pm

I'm pretty sure both taking off from a planet and landing on a planet is done in an in-engine cutscene, so I don't think it has any effect there.

No clue what it might do while you're in space though, someone with the PR beta should be able to answer that.

Take off and Landing are automated
I think the escape velocity was added in order to give the info a more pollished look. If you looked at the numbers you would have seen that alot of the worlds were much denser then Earth. We have a 9.8g gravity well, while the site quotes world with 11 and higher...Actually Humans would have evolved into short and stocky under those gravities in a generation or two 8)


I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the darkness at Tan Hauser Gate. All those moments will be lost in time like tears in rain. Time to die.

Whaa, seeing the name of this thread made me really excited: "Someone else has noticed the obvious imilarities between FL and the old Macintosh "Escape Velocity".. Now this (no offense to the thread poster btw )

*goesoffthreadtopic*
Anyone else has played EV? Or EV Override? Or EV Nova? Just being curios

While the 9.8 number is involved in the calculation, that is the actual "g" constant value of our gravity (9.8 m/s^2) at sea level. If you do all the math to calculate the actual escape velocity for Earth (from sea level) it's about 11.1 km/s (or about 25,000 mph). Since it's highly impractical to discuss something moviing that fast and being launched into the sky (basicly entering orbit without expending any additional power), it's not a practicle value at all. Another way to look at escape velocity is the speed at which you must travel to stay in orbit. At see level this is again, not very practicle while at the height the shuttle orbits, it's closer to 20k-15k mph and quite possible (no or little air resistance, nothing much to run into, etc.)

Yeah, I got hooked on EV like 5 years ago when I still had a Mac =P

I play it occasionally on an emulator called Basilisk II, works great if you can find a ROM for it. ( http://gamma.nic.fi/~lpesonen/BasiliskII/)

Nova is a bit slow on it, but the PC port of it is due out any day now.

Cool, thx for the link I'll definitely try it out soon.
And to all the others: THIS is a game you REALLY get addicted to Hope FL's gonna be the same

Just remember you'll need a ROM for that, you can download one ( which is technically illegal, so I probably shouldn't post a link here, but it's not hard to find ) or get one from a Mac you legitimately own with a ROM retrieval utility.

Oh, and the link to the progress log for the PC port of EV Nova is here: http://www.ambrosiasw.com/webboard/Foru ... 00013.html

Sounds like they're almost done.

Ha, I'll possibly just wait for Nova to be released for PC
And since the original EV worked fine on my.. ermh.. - VERY - old Mac (remember him wasting in the garage ), I'll skip the ROM and emulator thingy

But thanks for the info, nice not to be alone with that (great) EV experience

Brother Grimm,

Your right, and where your right your right, and you, you're allways right 8)

Actually escape velocity is needed to leave the earth, say for the moon. To get into orbit it's much less. So i retract and proclaim thus, if planets have less gravity, thats awesome. People wil tend to be higher, also since we evolved for 1g, anything lower then the norm will have great effects on your health. Although if your a couch potato, your muscles and skeleton will only go faster 8)

If your physically active, they your looking at a much better life expectensy (since your heart has to work less to pump blood to your brain)

Class, repeat after me: "Zero G, is the life for me" 8)

There are side effects: your bones and muscles get weaker if you stay too long in zero-g. Long-term astronauts make a zealous habit of working out on gym apparatus everyday while on zero-g to dampen this. And when they do get back on earth, they usually need muscle-rebuilding therapy.

Ya, right.
But if you stayed up there forever you'd be saving a lot of energy (without needing to rebuild muscles)...

*getsinterestingidea*

Finally I've got the solution for all the third world countries' food problems:
Letz get all these people into space stations so they waste less energy (food) because of 0 G...

Unfortunately it's not that easy :/

Actually...... The precise definition of escape velocity is the minimum initial velocity you need at a given distance from a planet in order to reach an infinite distance from that planet when the gravitational force (of that planet) finally stops you.

When you crunch the numbers it is only dependant on the mass of the planet and the distance you start at. (and newton's gravitational constant).

Post Thu Feb 13, 2003 5:43 pm

I seriously doubt that the size of the planets and their escape velocity will have any effect on gameplay. They just put that stuff in there to add a little color. I wonder if the populations of planets and stations will effect things. It would make sense for there to be more freight traffic between more populous planets than smaller ones.

Let's get those missiles ready to destroy the universe!!

I don't think so. This assumption is based on a widely spread misunderstanding of how evolution works. Nature doesn't respond directly to enviromental circumstances. It works different: every so often there are spontanous and totally random mutations in organisms which give em by chance slightly different abilities compared to the rest of their species. Sometimes it happens by pure conincidence that some of these random abilities actually give its "owner" a special advantage over the other members of its species. The result is that it has more chances to survive than the others, which make it more likely that it reproduces itself. If the genetic code of this ability is dominant and doesn't get eliminated in the next generations that is.

Over time (speaking of many generations) these new and more effective abilities spread within the species, suppressing the previous type of that species. Like i said this is totally random and normally only spreads when it really provides an advantage. This is called, as Darwin put it: "Survival of the fittest", meaning that only those survive who do fit best into their enviroment. Unfortunately there are different abusive interpretations of Darwins thesis, i won't comment on that, cause it's a whole topic for itself.

Anyway, that being said let's get back to the "higher people". I don't really see why taller people should have any advantages over smaller ones on low gravity worlds, thus there is no necessity for people or beast to turn out taller on these planets. Another thing: due to medical and technological advances there isn't a real evolution in humanity anymore. Almost everyone has the same chances to survive and reproduce himself/herself. Sure, people on Earth are becoming taller and taller from generation to generation, but that's more of a random effect of dominant genes as well. I didn't recognize a loss of Earths gravity in the recent centuries.

I hope i didn't bore you guys with this little digression.
