Gravitation

Well, WoB said that there are subtle differences between Kaladins Abilities and Szeths. I'd like to find out just what these differences are.

At first i thought Kaladin didn't need to worry about normal Gravity, one lashing and normal Gravity is just nullified. But i think Sanderson just didn't put emphasis on negating normal Gravity anymore.

Then i thought Kaladin used more Stormlight, as seen in him getting low on light after traversing the plains (terminal velocity is around 320km/h and is reached in seconds) which means the seconds, one or two minutes at most he needed took tons of "relashing." Also at the End of the book he needs quite much Light as per his own words, meaning 320km/h aren't enough (he needs several lashings) or he needs to "relash" really often. The thing is we never even get vague comparisons between Szeths and Kaladins consumption, let alone precise comparisons. And maybe Sanderson just didn't take in account that terminal velocity with only 1g is already 320km/h.

 

And that's basically it. Two things, both probably not a real difference. What do you think? What are the differences between their powers, and what is their impact?

 

Remember if you spoil something from WoR, use the spoiler tag. I think as vague as i described it, it is ok though, if not, tell me. This Topic is about the whole Stormlight Archive, at least the first two books, so i put it here...

There's no 'negating' needed of normal gravity in the gravitational lashing. What it's doing is essentially redirecting some of the existing acceleration; we can see this when Szeth redirects a quarter of a lashing upwards and gets half the weight. Kaladin uses two lashings (one up and one down) to achieve weightlessness:

 

 

Curious, he Lashed himself downward to slow further, then dismissed all of his Lashings except one up and one down. He eventually came to a stop hanging in midair. The second moon had risen, bathing the Plains in light far below. From here, they looked like a broken plate. No . . . he thought, squinting. It’s a pattern. He’d seen this before. In a dream.

 

Mathematically this is somewhat weird (up to 1 lashing, the magnitude of all of the acceleration vectors are constant, with a non-differentiable point at 1 lashing) but it's described consistently in the books.

 

Note that terminal velocity is dependent on the force due to gravity (since it's when force from air resistance = force from gravity) so lashing more to go faster is pretty reasonable physics.

Well, i would guess that 320 km/h would seem plenty fast for someone who hasn't even galloped (i think). Besides: it's not that you don't feel it, as you said the forces offset each other. While a couple G may be ok, the human body can't take too much. And even if Stormlight helps there, the pain would be quite high (imagine what happens to your eyes!), lying on air is way less comfortable than lying on the floor.

But the thing about not needing to neutralize gravity, i didn't realize that, nice catch. Too bad we don't know if it needs a different amount of stormlight to lash oneself into a direction one is already lashed...

 

I found the WoB about needing more Stormlight too, but i think we need more.

I'll have to think about this. I just would like to know more about the Bond, how surges work (lashing could be commanding a spren, but Soulcasting? I think not.)how the honorblades work. And i think we can speculate wuite a bit with what we have, we just have to find the clues :-D

Soulcasting is basically bribing a spren with Stormlight to become something different. The famous stick is an example of this, except it failed in that case.

I think that terminal velocity will be determined more by air resistance.

 

I think that the Windrunners can use the pressure surge to lower air resistance and maintain constant air pressure in order to fly higher and faster than Skybreakers.  This usage would be passive, and would constitute the main difference between Windrunners' and Skybreakers' use of gravitation.

 

In short, Skybreakers are Slow (at least when compared to Windrunners).

I have no doubt that Windrunners will be better in the air than the Skybreakers. Creating a vacuum in front, and a high pressure wave behind should make for absolutely insane speeds, especially when combined with gravity. They'll be running circles around bullets. But Skybreakers do have Division, which might close the gap a little, if not enough. Dividing the air in front of them can probably decrease air resistance to a degree.

I meant the whole going to Shadesmar. Or better said looking into shadesmar and having your spirit walk around there...

 

About pressure: that would explain why he needs more stormlight than seems reasonable, if he uses adhesion by instinct (and quite extensively, lowering the pressure to reduce resistance, taking a bubble around with normal pressure so he doesn't suffocate or even bleed out).

But that brings me to another point: why is the surge dealing with pressure and vacuum (so with pressure and pressure :-D) called adhesion? Adhesion is what happens with suckers, or if you press something wet against a surface, and it holds there (no pressure between the objects, normal pressure around, the water seals it). The thing is, thats a quite specialised application of pressure manipulation, and the whole surge is called that?

Perhaps the only manipulation of it that's been found is the Full Lashing?
