Chain Drop

OLD SCHOOL

[naceajtnik]

im here from vsauce

[falafel1995]

Didn't Galileo do something like this.

[GCErik]

DANG IT! i forgot to pick an answer! My life is ended!

[kazamazaz]

they will both hit the gound at the same time duh

[jknengr796]

g is the same. It is the location of the changing location of the mass center of the weight/chain that needs to be considered. It is lower along the line of chain. So of course it will hit the ground first.

[bigdipper117]

trick question the chain is to short to hit the ground :P

[Alexiey1919]

A lot of responses are only are considering one small aspect, you have to take into account how much chain is actually bundled up ready to fall and is not already hanging, how much wind resistance that chain would create with respect to how much mass it will add to the weight and inturn it's terminal velocity and also how far the weights will fall as that will dictate whether enough time will pass for that resistance to take effect, Galileo's results show ideal conditions in an non ideal world

[danyz92]

can i really know what is his name?

[RichardCuzz]

so that's where the chain for my wife went!

[willyumsstudio]

I'm going to assume that the chain is longer than the drop distance, since you didn't mention that factor.

[klangwii]

Theoretically the chainless one because it would have less wind resistance :P haha but NO, everything falls at the same rate. SAME TIME.

[Jackrules31]

i like these videos where we get to choose the answer. they're fun and they teach us.

[PookiePorn]

i live there

[Ennec93]

pointless absolutely pointless

[AussieGrower13]

chain weright

[karana808]

Awww man i was waiting then my screen went black........

[SuperApparition]

Fuck off.

[jchyip]

Same time of course. Google "Galileo Leaning Tower of Pisa"

[poppinfresh101]

If the chain is long enough to reach the ground, both will hit the ground at the same time.

[SoWastedMusic]

@poppinfresh101 wrong thec chain adds more weight

[WootMapler]

@SoWastedMusic Adding more weight doesn't mean it'll hit first. Come on I learnt this is 6th grade.

[SoWastedMusic]

@WootMapler you got to take into account that the earth is moving towards the objects aswell and accelerates faster towards heavier objects, everything may fall at the same speed but the gravtational pull would be greater on a heavier object.. this is my theory but i could be a million milles off ^_^

[WootMapler]

@SoWastedMusic hmm interesting

[mbilalsultan]

may be same

[commentnotapproved1]

Can you put the chain back on the dunny when you've finished?.....I need to flush..!

[bcphysics]

Hmmmm for one, the mass is changing... A perfect opportunity to investigate with a high speed camera ;)

[GuitarMelodiesSB]

Post the answer!

[1veritasium]

@GuitarMelodiesSB it is posted - but you need to be watching on a computer to access the links to unlisted answer videos at the end.

[GuitarMelodiesSB]

@1veritasium Ah, okay, nice :)

[howtoletsplayccrs]

@1veritasium

The add was in the way :l

[AshRothPhan]

Fuck im watching this on my ipod..

[faggortlum]

Depends. If the weight were to rub on the chain while falling, friction occurs, slowing it down. The chain must also be long enough to reach the ground and both weights cannot come in contact with the surface of the wall. If all these factors are satisfied and the bridge is very high, the chained weight will fall first as it loses mass while falling du to the shortening of excess chain, reaching terminal velocity faster.

[werdnativ]

On the one hand I think mass doesn't matter, they will accelerate at the same rate. On the other hand, I have this intuitive sense that there's an additional force near the hanging loop of the chain where the links are prevented from accelerating freely and they pull down on the free chain above... creating a "whip" effect.

[werdnativ]

To clarify, I guess I think of it like gravity acting like a pulley force on the middle of the chain, which would pull down the free end faster.

[30763076]

Well according to gravity force, if its above a certain amount of meters they will hit at the same time

[Spraynwipex]

Nope, the one on the chain falls first.

He's my physics lecturer :)

[p00pkrap]

it will both hit the ground at the same time

[dzloll]

if you listen to the sound around 0:34 theres only one sound, suggesting they both hit the ground at the same time.

[dzloll]

how longs the chain ? =)

[ghrpdx]

I'm going for same time, but the suspense is killing me ... it's like "Who shot JR" all over again!

[sillylittletroy]

Same time-ish. One may encounter more drag than the other.

[viridiseqeusequitis]

The free weight should hit the ground first, I think.

[JMercuie]

i feel like i should point out, that you should let your facial hair grow back out again. must be said! oh, the chain thing is cool too. :D

[ApolloEdits]

when will we know?

[SLEEPLESSHIPPIE]

WHAT HAPPENS!!!!!!!!!

[chrissythebest08]

omg what happens?!

[SLEEPLESSHIPPIE]

LIKE HYDROGEN



[SLEEPLESSHIPPIE]

first?
