Chain Drop Answer 2

[MultiGreen213]

a question: If bungee jumping with that amount of acceleration made you feel pumped up. What do you suppose the feeling would be if the acceleration was the speed of light or faster?

[HeadingForTomorrow]

Wow, you guys study this in college and need classes to tell the one with chain will fall faster? Son I am disappoint.

[BobChimichanga]

Dear Newton,

fck you i dont need college ^_^

[jsJavaScript]

Now I'm really disappointed you didn't test your theory with a non tethered bungee jumper~!

[PhobiaPhobo]

Newton.... u fked up

[severuxtrololo]

YES i was right!

[ASTROTZUR]

Can you please point me to an explanation of how to calculate the new acceleration rate?

[1veritasium]

@ASTROTZUR you can find a lot of good explanations on the web, just google 'acceleration of a bungy jumper'

[NorthPolePyro]

the chain adds weight

[Aviatorsmith]

@NorthPolePyro The added weight does nothing.

[Junglemanpc101]

@NorthPolePyro It's due to tension caused by the chain.

[Matticusjk]

@1veritasium Is that due to Newton's Third Law? The force going up has an force equal in magnitude, opposite in direction acting on the end of the chain the weight is attached to?

[Chanvlan]

@1veritasium @2:10 that is a place near Queenstown New Zealand is it not?

[2s7a2m7]

haha it's not like they made you climb back up XD

[aden302000]

The acceleration is greater than that of your soiled underwear!

[jlmknight]

the poor grass

[FailDrummer]

I though they would fall the same speed! Despising the fact 1 could have more air resistance.

I failed:D

[Knives219]

because chain adds mass. m*g niggs

[steel5w]

@Knives219 nope, that's not a factor. If the chain weren't connected to the rail, both weights would accelerate the same.

[trppmdm]

@Knives219 nope. Mass doesn't mean anything to gravity. Google about Galileo galilei

[joshua123ldrago]

i always pick the one that sounds wrong

[marquez91]

2:08 3, 2, 1.. OMG!!! AAAAHHH!!!

[daniel7gt]

i was right!

[michael06070]

Ring on the pinky, that's whats up.

[RemedyGaming21]

If you dropped a 100 Lb Cinder block and a 50 Lb one from over 50 Ft, which shall hit first? Both will at the same time unless you have something attached to one like a chain/rope.

[Dragonite202020]

do bungee without rope

[GuitarKasper]

Now try the weight experiment by bungee jumping with two people

[aygtets]

@GuitarKasper It should be the same as bungee jumping with one person.

[notfree25]

no i didnt see that.. the ad pop-ed up just in time.

[FameMods]

Owwww, you hurt my mind from 1:25 on wards :(

[soulsnatchersz]

BLASPHEMY

[iTzMist]

Yes ! I got it right because I saw that this one had a different youtube link

[Noah2277]

thumbs up if you got it wrong and came back to change your answer

[AussieGrower13]

woooo hoooo see cause the chain pulls it as well!

[BurnNotice3210]

yehhhhhhh

[minecraftfan01]

i won

yay

[CleanDrop]

i am so smart i am so smart, s m a t i mean s m a r t - quote by homer simpson

[megabaconman321]

im smart

[ushmo10]

yes knew it

[death4hiro]

GPE = KE

GPE = mgh

where m of chained weight > m of free weight 'cause there's the weight of the chain acting upon the weight as well (can't get a better phrasing, srry)

KE = 1/2 mv^2

energy conservation law where all GPE gets converted into KE

hence, final v of chained weight must be more than final v of free weight

thus, acc of chained weight must thus be higher than free weight as well

conclusion, chained weight hits ground first...

... That's pretty much what happened in my mind... hehe

[Revektion]

i got it on my first try, do i get a cookie?

[rolficus]

fuck im smart

[jaymayhoi]

i just thought the chain added more weight haha

[ushmo10]

@jaymayhoi ssmae

[ilikemunting]

im right, now wheres my prize

[tiliqua]

considering you showed this to us during lectures last week, not too surprised I got it right ;)

[FurkanKhan100]

chain was pulling on the wieght

[enmart1234]

cha ching!

[msms47]

u look better with beard :p

[Freitag13052010]

statistics say one third of all viewers got it right... learned something today! thank's

[blackwest69]

yay i got the right answer intuitively ! but i didn't know why until you explained it, thanks derek !! it was awesome, love it :)

[Okora11]

those weights....been through a lot. congrats!

[Skeluz]

Winners, unite!

[Arghira]

@Skeluz I'm a winner too but for the wrong reasons....

I thought that the chained weight will go faster because...it's...in a way...more aerodynamic

[Skeluz]

@Arghira

Ok, time to confess.

I thought it would be slightly faster because the chain would stir up some of the air making every object after it go faster. The same effect that birds use when flying - The Flying V.

We chose the right door for the wrong reasons. Still a win! :)

[kylie9022]

I went bungee jumping there at that bridge in Queenstown, the water was much more blue on the day i went and it started to snow

[bloodysaph]

ive been to that bungee place in NZ :)

[simoncapon]

zing. I wonder why I clicked this first.

[bloodysaph]

@simoncapon

yeah i wonder, trust.



[xLDH1109x]

third

[danielcarmi305]

@xLDH1109x you lost. lol

[johnny52472]

yay
