Interface between artifical grav and real/no grav?

[Oaty_bars]

Mass = gravity
Mass = resistance to inertia

Right?

Wrong.

Gravity is related to mass and radius. Inertia is a property of mass. Gravity is not mass. "resistance to inertia" is fairly nonsensical - Inertia is itself resistance to change in the state of an object's motion, you can't have resistance to a resistance . .

Mass = resistance to inertia
(correct it takes alot more energy to more a more massive body)

Gravity is related to mass and radius in effect
resistance to inertia is a property of mass,
Gravity is not mass, but mass is always Gravity
A body in motion is still resistance due to its inertia,
But the degree of inertia is in relation to its mass

Mass creates gravity
Gravity creates inertia

Wrong.

Gravity is "generated" by Mass, yes. But Gravity and inertia are not related - mass and inertia are. .

No both are, Mass creates Gravity, Gravity creates inertia via attraction,

Oaty - it's black box time; none of these are feasible but any way to do any of them implies being able to do all of them, they are the same thing. Don't confuse the technique with the effect or field of study.

As for the stuff about magnetism and inertia - wtf? You're completely off-base and need to go learn some physics because, politely, you're talking out of your arse and seem especially confused about inertia.

Okay, saw your second reply and you really need to learn to read what we wrote and digest it. Honestly, we know what we are talking about you really do not, so please either read our replies or go and study an 'A' level or equivalent text on physics.

I'm going to try this one last time, because I have a feeling I'm wasting my time here.

You are using statements of equivalence that are not true.
There is no such thing as "resistance to inertia" - there's just inertia. The resistance is to a change in the state of motion of the mass. A body in motion also has momentum as well, but that's not inertia.

Gravity is "generated" by Mass, yes. But Gravity and inertia are not related - mass and inertia are. .

No both are, Mass creates Gravity, Gravity creates inertia via attraction,

Wrong. Gravity does not create inertia, period. Inertia is solely a property of mass. Get it out of your head that mass and gravity and inertia are the same thing, because they really really aren't.

Dude, everything is electromagnetic force

You're not one of these "Electric Universe" crackpots are you?

 

[Gaidheal]

Electric Universe? It sounds like a great setting name...

Sounds more like a hippy rock band to me .

Go to bautforum.com (in the ATM section) and see how crazy these guys are. They think that absolutely everything in the universe is explainable by electrical forces. There's no evidence to support their claims whatsoever though, and if you say they're wrong they start on the conspiracy theories. They're as loopy as the guys who think that aliens built a face on Mars.

Oh, wow! That was a laugh, thanks. :¬)

I'm going to weigh in on this too, I'm afraid, Oaty. I don't know whether you're trying to translate from another language than English. If you are, it's a brave effort, but sadly not quite hitting the mark. If you're not, then you've hopelessly tangled your terminology. Have a *careful* read of what EDG, Gaidheal and Dave Chase have written, because their explanations are accurate reflections of the physical universe as we understand it currently.

Mass = resistance to inertia
(correct

Incorrect

t takes alot more energy to more a more massive body)

Correct. But not a sequitur from your previous assertion.

Mass creates gravity

Correct.

Gravity creates inertia

Incorrect. Gravity is an *attractive force* between two masses. Inertia is an inherent property of mass (as far as we currently understand it.

No both are, Mass creates Gravity, Gravity creates inertia via attraction,

You may assert this, but you're using the word "inertia" in a different way to everyone in the world who knows what they're talking about. Or you're wrong. Gravity actively works against the inertia of the two bodies that are attracted to each other: it creates a force which accelerates the two masses towards each other, *in spite* of their inertia.

Please google around, even to wikipedia (it's usually pretty good on things like physical constants and terminologies) and check what we're saying if you have to. Or you can trust us: we've no agenda to try and mislead you. But honestly, it looks like your actual grasp of physics is a bit confused and these forums are pretty prone to didacticism, so we're only trying to educate. It's nothing personal.

 

[Gaidheal]

Wikipedia FTW! *nod*

Just don't rely on it (i.e. it is not an authority but it's an excellent reference for general understanding and it's rarely, if ever, wrong about basic facts, constants or terms).

 

[lastbesthope]

no,
Mass creates gravity
Gravity creates inertia

it doesn't matter that Mass is resistance to inertia, we are talking about Gravity, and not the resistance of that body of Gravity

You do need mass to get gravity yes (Ignoring any grav field generators SF may allow)

But you do not need gravity to get inertia. Inertia is a mass's resistance to acceleration it is a property of mass and movement.

True, but I didn't say contrary :wink:

You said "gravity creates inertia" which is untrue and is indeed contrary to "you do not need gravity to get inertia", so, I am calling you on this and hopefully ending this two thread mess.

What Gaidheal said :lol:
