Newtons's Cradle for iPhone

[MrBestapps1234]

99 cents i guess again

[peop23able]

LOL

[ThePizzaman1218]

is it free

[ThePieMan159]

@ThePizzaman1218 no its 50$ lol

[7XxshadowxX7]

(this might sound really weird but) all of the balls are leaning to the left so FAIL! they are all supposed to be in the middle >.<

[Biltospill]

@7XxshadowxX7 actually you are completely wrong. the angle the ball are in relation to the cradle have nothing to do with the law. you can test this by holding a cradle in a precarious position and begin the cradle movement. I hate to expose your stupidity but this should be fairly obvious to anyone watching this video, or perhaps your a simpleton?.. either way, you fail(i hate that word) idiot

[matijasajko1]

theare was 39 likes, and 39 unlikes, and i liked, so you now havw 40 likes and 39 unlikes :I



[warlockboyburns]

the sound is horrible.. sounds like insects

[chemlink1]

I am asking permission to show this video in my science classes. It seems to fit well with the subject material. I appreciate your consideration.

[1TheStuffChannel1]

@chemlink1 Use a real Newton's Cradle. Not a video of a virtual one.

[ViRGiNsOnLY]

that fucking sucked

[StodgierDonjr]

i love newton cradle balls

[thespaceboon101]

it would be cool if you can change the amount of balls

[ajek2323]

fajne ta aplikacja

[HomeworkSlipMan]

bewbs??!!

[slimboy808]

I ALMOST FELL ASLEEEEEEEP...

[chilliman07]

Just as bad as it is on Android!!

[JEIWILBER]

So incredble !

How much can we aplly math to the machines ! ! !

[TheMIGUELVALENCIA]

me and my friend were using this on a bus to a field trip and it started going relly fast and we couldnt stop laughing like we laught non stop the whole hour on the bus til we were there

[TheMIGUELVALENCIA]

@TheMIGUELVALENCIA right

[MominaRani123]

1. pause the video

2. press the up adn right arrow keys (try more than once)

3.Enjoy a game of snake.

THUMBS UP for truth

dont ask how i figured this out..i got it from anorther video

[PeltzIsland]

@MominaRani123 dude thats crazy

[caroline4448]

i like the three ones

[sdutango]

why is it leaning to the left?

[smilesmilecrocodile]

@sdutango Because the phone was probably tilted slightly to the left.

[DouchieMcDick]

why is newton so famous for dis shiz?

[Mandaramaster]

@DouchieMcDick -_- look it up

[LLskater]

EPIC FAIL

[shopsnacks]

my science teacher has these

[jastheaceboydie]

@shopsnacks i bet ur love to play with ur science teachers balls

[XxGodxIchigoxX]

Great, I want to be a scientist, and I have to learn physics, so yay for Newton (No? Okay then).

[erjuanjojj]

how did you get it?

[ThePieIsLie]

Why live your life when you can stare for hours at the newton's cradle in your iPhone. :D

[charliekid5]

kinetic balls is better

[sweetandmematch]

kinetic balls is better but still pointless

[snyper105]

this is a terrible app its very laggy

[FiggleSmit]

@snyper105 lol at people using 'lag' wherever there is ANY form of delay, removing any meaning of the word.

[Silverfire321]

For those who aren't interested in physics, just like a real Newton's Cradle it might seem completely pointless, but for for people looking for a demonstration of Conservation of Momentum and Energy it's a neat little combination of modern technology and classical experimentation. I wonder if the app's makers programmed external forces such as gravity into their hypothetical cradle, it's hard to tell from the video.

[timemachinedrummer]

@Silverfire321 jaja just learn it from science class or what

[Silverfire321]

@timemachinedrummer I guess 4th graders like you still call it science class. But for university students it's more specific than that.

[timemachinedrummer]

@Silverfire321 I called it science class for you to understand fucking asshole

[FiggleSmit]

@Silverfire321 Gravity is not an external force in this situation..

however air resistance due to a drag coefficient acting on the respective moving balls would be. And from the looks of it, the programmer did not take such things into account. It is a good demonstration of the conservation of energy, but I think some would see it as pointless because it doesn't work for ever in reality and they may not understand that the hypothetical model assumes 100% efficiency of power.

[Silverfire321]

@FiggleSmit In fact regarding my initial inquiry, of course a gravitational force has to be programmed into the cradle shown here or else there would be nothing to induce a ball to fall once it's been released from its apex! As for efficiency, if the programmer did not program air resistance into this model, then I suppose you can assume that the cradle is in a vacuum. If that's the case, however then we shouldn't be hearing a 'clicking' sound either.

[FiggleSmit]

@Silverfire321 Sorry, I didn't make myself clear; what I meant is that though it is programmed to represent gravity, it would not be programmed to respond intelligently to other conditions in the way a gravitational field strength would. It would more likely be a conditional statement to tell the ball at each end to follow the coordinates of a specific trajectory when the ball when the opposite ball has returned. Very true about the clicking thing =)

[Idiotsmakemesad]

@FiggleSmit No, I don't think that's the case at all. You can actually see it make reference to the external force of gravity via the accelerometers in the phone. Look at the start you can see the balls leaning before they are even touched. But even if it didn't use the accelerometers I would still expect the model to be a lot more complicated than a solitary 'conditional statement', it needs to be to give any sort of realism. That's why all modern games contain a lot of real world physics.

[flamerx5000]

whats the point?

[crytos]

this is on Android too.

[paldinkos]

wow we need 3 Ipods 1 piano,1 guitar,1Newtons's Cradle for band

[Kopyttek]

Sound not synchronised with the video :|

[thomasdfghj1]

youtube resynchronizes

[xxxcagriersozxxx]

no lol. it ownz like hell

[ayesha36]

Cool! i just love the fascinating idea of newton's cradle. im downloading it right now!

[Jokerluvr28]

it looks boring, but i kinda like it... :)

[Jonathan619rp]

Dude It gets blocked. My itouch gor crashed because of this application

[flatstanlyADvanced]

uhh... cant even think of what to comment for this one..

[phantomlord1988]

me either

[bigshowsxxlwin]

trixxer LOL

[koolerz1569]

how do i get it steady ???

[mudaphucker]

that and weed = buzzy

[amna72391]

LOL that just fuckin made my day

[pure5152]

it's cool... but i think there should be an option to turn the gravity tilt "off" , it gets annoying sometimes

[LuigiVN]

COOL!!!!!!!!!!

[rawn321]

Tnx im downloading it, ;)

[halomaniac223]

nah its cool

[tiankr]

stupid app
