Could a human with fast speed run on walls? Thread

You've gotta have some realism in fantasy. Normally someone can run on walls for a very short time. But with increased speed?

IMO we run with bouncing so you would still bounce of the wall no matter at which speed. Then again if you run against a wall with fast speed you would make a momentum to that direction and then you could run on walls longer. So unless running at speed of light you cannot run on walls as long as you would like.

Am I right?

speed doesnt matter (you will get further tough but thats because the momentum takes you there, so even if you touched no wall you could still get further) so so thats out of the question

Then again if you run against a wall with fast speed you would make a momentum to that direction and then you could run on walls longer

this is not true
if you walk you practically push yourself a bit up so if you run on a wall (speed doesnt matter) you push yourself away from the wall
to walk longer on a wall you need to make sure that your momentum keeps you on the wall
so before you hit the wall you need to shift your weight to the wall
the momentum of that shift pushes you a bit more against the wall so you could take some extra steps (not alot more, maybe 1 more or so)
last time i tried i could take between 4-6 at my best, when i dont did my best i could get 3
but yeah, long story short

Like you said, it's just a matter of time before you "push" yourself off the wall again.

No, it's not possible to run on the walls, unless you are runnning inside a cylindrical or spherical building. You would have a higher kinetic energy and oppose a centrifugal power versus gravity. Gravity moves objects at 9.1 meters per second, I think. So when your centrifugal power becomes higher than gravity, gravity is overruled, but speed alone won't do the trick.
Only, if you live outside the set of rules we have to adhere too, like Dr. Manhatten, you can cross over natural laws and bend the rules of Physics. On a nano-level those rules all turn into their opposite and become extremely unlogical, anyway. So maybe Neutrinos and Quarks can do those tricks, but we cannot.

9.8...mostly depending on your location(closer to ekvator(you know what I mean)/poles)

/me ok so this character won't walk/run on walls...

I can see it now people in sonic and/or naruto costume running on walks.

It's a simple case of Actio = Reactio. You push yourself away from the wall and as long as there is no force pulling you towards the wall again it doesn't matter how fast you are since the force is perpendicular to your running velocity so velocity has no influence.

May be a bit off topic but science is an explanation of reality not the other way around.

to run on walls you need sticky shoes and really strong legs ...

Not exactly, as this kind of defies the rules of physics.
If you were interested in a type of wall running though, find some Ninjitsu books on it, because there is, in fact, a technique to it.

Uhh.. no.

haha

No to me or the topic in general?

Topic in general.

Well I'd still go with reality over science. Example:

If I jump off a tall building, science says I will fall at 9.81 m/s. Reality says I will die when I hit the ground.

Hm... then I prefer Mythbusters... they comine both... and manage to blow up windows in an entire village while doing so

Its been said, if you run in a spherical building with a certain speed the force is enough to keep you on the wall.
You could achive that by adding some sort of wing to increase the pressure you cause aswell. Like Formula 1 cars do, those cars keep pressuring the ground like a 25t truck does. In addition to that Formula 1 cars can drive on ceilings if they travel with more then 160km/h.

I was about to mention wings / fins.

Yes, that's also something else. As I said above "as long as there is no force pulling you towards the wall". Wings translate speed into a force into a certain direction. But to get pressed to the wall you need to run at the starting speed of an airplane. In that case you can just run on the floor and slice and dice all next to you before they even knew what hit 'em

The way that the human beinghs walk and ran is using force against the floor, more force more speed, but of course the gravity is more power full than any muscle, so but if you try to go faster in a wall you will jump off it, if you do it slower( or not ) you fall

I had a friend who could run on the side of his house, albeit very shortly. So yes, someone COULD run on walls, but not for very long before they smack into the ground again. The floor provides the launch point, but momentum is what carries you on the wall. Doesn't matter how strong your legs are, gravity is stronger and will smack your hopeful ass back into the pavement.

Played Prince of Persia?
That's what I call TRUE unrealism.
They even made him "scratch" the wall while running, even though, realistically, that would only decrease speed.

I suppose that would be another method. Digging into the wall to keep yourself attached. I've seen some cat's climb across walls like that. I think thats how squirrels do it as well.

That is possible, but its your centrifugal force thats allowing you to do that ... however im not sure if its physically possible for there to be spherical container big enough for a person to fit in, yet still be able to generate enough force to run on walls ...

but is a couple of steps "running"?

also, how vertical does a wall have to be in order to be a "wall" ... I remember we used to have bleachers in our school gym that when folded in, sloped out from the wall so it wasn't completely vertical about 60-70 deg ... We used to run on the side of those bleachers all the time ... and we could get at least 4 steps in ...

Actually, even if you were in a sphere that was possible to run up/around (going around in a 360 circle from top to bottom) you will gain more and more momentum/speed and eventually your legs will get tired/can not take the excessive speed and you will either trip or fall. That is, unless you can keep a constant speed throughout (plus, if the sphere is not transparent, you will most likely get confused what is up and what is down and eventually fall. And even if it was transparent, you would get dizzy, unless you try focusing on a fixed point somehow.).

That was a great description. (not being sarcastic)
