Mythbusters - Car crash force

[HarvestmanVinyl]

Ah, Daewoo, the company that made the Chevy Aveo.

[Hammond1467]

Omg at 1:18 the yello cars' front looks like a smart car

[69roadr]

wow, you guys have a great job!

[audia8long1]

DAEWOO NUBIRA

[fiesta181]

Actually it's thumbs up to Emilie Du Châtelet. She introduced the square missing on Newton's original equations.

[Grenonator]

Actually no, twice as much energy is created by a car hitting at a wall at 100mph as opposed to two hitting at 50mph... Ke = 1/2 m x v2.... Velocity squared is the key here

[looneyirish007]

you dont need to do this test as its a question in the car licence, who doesn't know this

[Ascii89]

no adam you were right, 2 cars hitting eachother at 50mph create the same energy as one car hitting a wall at 100mph :P u just worded it wrong

[DROLL30]

its red not orange

[ADEdge]

For the sake of science, 2 cars head on at 100mph? :D

[nunu13001]

0:49 look at the car fart.

[Sierra304]

Car is Daewoo Nubira

[jesusfields35]

This vid is a favorite on Jordan

[Kersenblik]

People with top comment are ugly and they stink most of the time!!

[tankermottind]

Can a Daewoo reach 100 miles per hour?

[felsner1]

Interesting experiment.

[Cerpth]

If a car that moving 50mph will hit the wall that also moving (on some platform) 50mph, then car will looks like crushing into wall (that doesn't moves) at 100mph.

[egilpl]

@Cerpth True, also most objects on the road to which you might crush into will consume some of the energy of the crash just like another car. That's also why "Project EPAR Lagiewka Bumper" works

[scorpiusb]

how can they compare crashing into a wall with crashing into a car?

oh well.. the test was still informative

[Smonjirez]

Beuh. The physics are just so simple. A car crashing against a wall is just the deceleration from 50-0 in a very short amount of time, causing the damage. When a car hits another car head-on and they both go 50 mph, they both just decelerate from 50-0, just like in the wall-crash. Thus, the damage is equal.

[unix0592]

@Smonjirez I whish I could give 5 thumbs up for you.

What concerns me is that in the test both cars were the same. I think if one of the cars was 3 times as heavy, then the heavier car would get half of the damage (compared to hitting a wall) and the lighter car would get twice the damage due to conservation of momentum between both cars.

[seth5220]

Interested to see damage at 55, 60, 65, 70 and 75 mph

[NichoXD]

3 dislikers are the dummys

[girlie347]

@NichoXD always sad so see a gay with nothing to say. Others make meaningful comments, you can't think of anything else to say than saying how many dislikes there are. Must be hard living with an empty head.

[GalacticMuppet]

Also shows how crap American cars are.

[glhs386]

@GalacticMuppet Daewoo is Korean.

[GalacticMuppet]

@glhs386 I think you'll find Daewoo is a subsidiary of... wait... have a guess... given up?... General Motors.

[PerformanceCars1FCH1]

@GalacticMuppet they only bought it so they could have a market in east asia were most people dont have alot to spend on cars (With exception to Japan). Now why they sold it in the US I don't know.

[theoriginalopo]

Now test what a car going 100 mph crashing into Justin Bieber looks like.

[tobisama]

¿But in a 2 car front collision 100mph - 50mph what would be the damage? The damage would be divided by 2? equivalent to 75 mph each car against a wall?

[GoRaGeBbit]

@tobisama I would think so

[Popikawaii]

@tobisama

The collision speed is simply the total difference between the cars, regardless of who is travelling faster. In your example the total speed is 150mph

The damage however is based upon total mass. The bigger a car, the less damage it will take, and the more damage the other one will take. If both are equal, then yes, 75mph into a wall would be rather accurate. If one car is twice as large, the split would be equivalent to 50mph/100mph into a wall.

[Schmich87]

If instead of driving a car at 50mph into a wall you do it against a stationary car, would that result in the cars feeling a hit similar to 25mph against a wall?

[mgoogyi]

@Schmich87 :

I think the answer is yes. 50mph into a stationary car is the same as 25mph into a wall. In the first scenario the two cars would move together with 25mph after the crash (sum momentum must remain unchanged), which means the hitting car would loose half of it's kinetic energy, that's the same as againtst the wall.

[metalgear32]

it is easy to understand, they both shared 100mph momentum... so 100/2 it looks like 50mph hit to static obstacle...

[benjamintg00]

now do a volvo :D

[nick081980]

don't buy a daewoo. or any gm. new korean gm,opel, holden, vauxhall are all deawoo.

[hippierdude]

y does jamie sound like hes speaking klingon?

[SteelCity1981]

It's a daewoo. Those things were considerd poor when the iihs crashed them at 35mph lol

[ambulanceamateur]

EvilSOB is totally correct. Each car absorbs its own half of the impact, so as each was going @ 50mph, that's what they look like.

To make it even more interesting, one of the cars should be rigged with a well-supported steel plate on the front. It would then absorb none (or at least very little) of the energy of the collision. The other would get the full impact of the 100mph shunt.

[UerMom]

Orange car? It looks pretty reddish to me..

[bigodinho86]

@UerMom There is yellow car and the other car, do U need more info ? :P

[werdchester]

3:34 they jumped that wall almost identically

[elpin1]

@werdchester I wonder what people don't notice sometimes :-)

[CarBoreBoy]

@comedyforideots Daewoo are Korean. If you're surprised by that then you would also be surprised to see how most American cars from the same era (early to mid 90s) fold like concertinas. I was surprised these 'orrible Daewoo things didn't destruct more at 100mph closing speed.

[iAmPwny]

i thot carmagedon was wen the 405 shut down

[haroldvideos]

it's a DAEWOO

[comedyforideots]

@haroldvideos chinese cars arnt very strong....

[baeronautics]

lol at 5:37 look at the action figure in the yellow car!

[OMIGOSHTHISISSTUPID]

0:28 = hardcore

[frankyoriginal]

O MY GOD!! Well... KE= 1/2MV2

[ThleTruth]

its a great question, jamie has no reason to be ashamed and he knows it...i thought it would be a slight bit more damaged than the wall, but i see where they are getting at, and it exactly right..and its amazing to see

[EvilS0B]

I would also like to see this revisited.

I would like to see the test done with one car travelling at 50 miles an hour,

and a 'brick wall' substitute TRAVELLING AT 50 MILES AN HOUR...

[adiosk8r4evr]

@EvilS0B yes, this is where it'd be different. The car, opposed to a moving brick wall, absorbs more energy, so with the brick wall, the car would obtain more damage. Energy is conserved in this situation, so you get my point.

[nocluewhere]

1 out of 10 people I have asked about this, got it wrong

[Topfueltrooper]

lol* Daewooooooos fail.

[Invinciblegame]

But first car crash in wall. What look car if he hit static car in 100mph?

[Davidbutter]

@Invinciblegame What?

[SierzantYelonek]

@Invinciblegame they should do this ... i think static car will get more G's than a car that is moving. They should also do next test by adding some weight to one of these cars
