Physics of Football

[grunder20]

Never thought football had Physics.

[GreenmeGo]

A good touchdown

[thegreeensky]

that was a bad hit.. but still a nice game...

[nelrish24]

waw

[andrewvanderleest]

He forgot to use sig figs.

[AdognamedOp]

Kinda takes the thrill of the good hit away, that math nonsense..

[manurulzz5]

someone check this dudes math please

[MrGish1]

@manurulzz5 It would be kinda hard without the raw data

[SnoweyMan111]

@manurulzz5 Why don't you do it? I won't bother. i trust him. I could go thorugh his calculations and simply put the divisions into my calculator and see if he's right. but his formula's checks out. So I won't bother no reason questinoning a professor in most cases. Id estimate it to something around what he got.

[xJx3g3xHx]

Nice vid. Glad to have him with the broncos. He reminds me of Ed McCaffery.

[LancerEvo10Fan]

Wow, not too many receivers in the NFL can hold onto the ball after a hit like that. Glad he's on my team now. Go Broncos

[TenchuXmusic]

Physics + Football... this is awesome.

[sweetfreakkelsey]

broncos!!!!:))

[Asolovieff38]

Cal still won though

[castusalbuscor]

How about you join the civilized world and use the Metric system! No one uses the Imperial system any more

go hawks. minnesota is for pussies

[mnvikings42869]

@kirkferentzrocks ur a fucking pussy go gophers

[IvelliousandValai]

@kirkferentzrocks And your Hawkeyes just lost to the Gophers...despite leading in the 4th quarter...Looks like your big tough Hawkeyes couldn't handle the Minnesota cold...And you call us soft?

[michael22414]

I'm a cal fan and boy, that is the toughest receiver in college, I hope he does great in the NFL.

[zoso8]

wow ur tough

[HwarangOfFaith]

Tell me about it.

I just hate how they make this seem like this is soooo intricately complicated and deep in scientific analysis lol.

[zoso8]

@HwarangOfFaith but u didn't

[Timpy2000]

holy fuck 10 g's, thats a alot of force

[jayry55]

even though he held on and got the touchdown,

Best beat them

[trabant1331]

yah , i dont know the rules but doesnt he outside the touch down area ?

[jayry55]

what?

[DJWWMU]

He managed to get one foot down in bounds at 0:23 so he was "in" then, as long as the football crosses the plane of the end zone ( touch down area) before his knee hits the ground, he scores.

[trabant1331]

axaaam i see now- thnx a lot "DJWWMU"

OMFG I Hat Math... 1:20

[kip2938]

decker the pecker

[maxir9]

that was not a touchdown

[pilly651]

his leg hits the pylon thats clearly a touchdown

[2009ForJesus]

[therealrichbitch]

I know watching the guy run into him had to hurt....TOUCHDOWN

[BWMiC]

fuck physics.

[9701davidp]

No way that was a touchdown!

[tommyle5]

his leg touched the cone.

[SimX9000]

well duh, who couldn't have figured that out

Go Bears!

[absolutsauron]

yes. the hit made decker weigh more. because it was so strong it made gravity pull harder on him.

[JonnOvitt]

decker shaken up cuz he got HAMMERED! XD

[Frostycool1]

those are some hands

[solgearx]

And they say rugby and soccer players are tougher, no way in hell. Football rules all.

[niksajanjic]

@solgearx

Typical American sport, only speed and strength, no intelligence or technique whatsoever, except quarterbacks. Every player needs to be doing only one thing during a whole career, but still that's the only way for those dumbasses(most of them are) to finish college.

[garrenshot]

i watched this

[randy670]

well he's a great wide reciever because I would have dropped that 9.9/10

[lavenderflavored]

check out my video and sub, if i become partners with youtube, half of the money i make will go to charity, ill def make sure to sub back.

[dellimel809]

it wuld be a td in da nfl cuz he hit dat orange td stick

[Starchaser10]

It was definately a touchdown. His foot toe tapped at the 1/2 yard line, well in bounds. You only need 1 foot in college ball. The ball does not have to cross the goal line between the pylons, and he doesn't land out of bounds until he was 2 yards past the goal line. He maintained possession through his landing. It's a TD

By NFL rules, it wouldn't be a touchdown, but that is irrelevant.

[thefatmanshow]

dayum. i would be dead from an impact like that

[Ps3KiNgJr]

Great video 5*

[mynamecouldbegeorge]

was not a touchdown.

[kingrazz2222]

it was

[macomighty]

banana

[oxhornfan1337]

umm its a touchdown because he hit the orange thing which means he corssed the plane.

[ZzCalebzZCM]

OMG, physics FTW!! Like I'm totally a n3rd and I just love physics. OMG, OMG.... *sigh* :) Merry Christams everybody!!

[jmeh1128]

if ur looking for a good laugh, check out my videos. newest video uploaded is called snow-bowling. its hilarious. check it out

[Cryp]

How about introducing the FUCKING METRIC SYSTEM in the USA.... It's absolutley annoying to see respected professors perfoming arithmetical calculation with this outdated system!

[jezuzfreek777]

shut up

[j0llygr33n]

pineapple sundae

[rachidizere]

owned

[thescout93]

Wasn't a TD he was about a quarter of a yard short. But thats not the point of the vid :)

[Lizzy4Rizzy]

dude this was an awesum breakdown! Mr. Replinger will so love this...I guess he's a football man too...

[Tips4Cube]

10 gangsters force

[Boeing121]

no way was that a TD

[freesk8]

Yay, Physics!

[jhaze918]

has youtube gotten slower for any1 else???

[Tips4Cube]

yup way slower and i have unlimited bandwith !!!

[olip5]

who fucking cares that shit???

[redx245]

was that really a TD

[Jraf94]

you forgot your apostrophe and your period, genius.

[Daniel2415]

10.78 gs is precise but it may lack accuracy since the prof could only estimate the distance with an uncertainty of half a foot from the videos. The announcer didn't take very many science classes, because he grabs onto 10.78, although it isn't meaningful if the actual force differs by say half a g

[miamiboy67]

10 g's?? SHIT!!!!

[Necrofear100]

Visit my channel for nice videos and subscribe for more.

[Gangdk]

F*CK! 10.78 Gs?!?!?!? OM*G!

[KaMakuakaneNui]

haha wtf o_O? so i take it that it was a big hit. no im jus jokin nice breakdown.

[JoelWhy]

That's a fantastic vid!

[cookadook]

i think im actually dumber from watching this..

[ShinobiTennis]

do you want free stuff such as ps3's, clothes, ipods, xboxes, purses and more message me your email because it is invite only for an invitation to lockerz . it legit as i got my i pod touch and ps3 from it

[ThePrincess2love]

go to my c.h.a.n.n.e.l see da vid on britany murphy... show some love to this late beloved actress... she will be greatly missed...plz make sure to leave ur personal feelns on this topic

[ajhernandezh]

theres a misscalculation, i suggest to make a review. those calculations were made assuming velocities in oposite directions, there's an angle that wasn't considered...the force is less than 5 G's

[rcgkids1]

In English Please.

[21leftcenter]

like the U of Minnesota knows anything about football...

[fussi90]

he felt that force for like what ? 0.3 - 0.6 seconds ?

[longhorn0213]

who gives a shit you dorks its "football" he got the tochdown luckily he got the tochdown or we would not give a crap about it!!!

[heymanhaha]

What is G force? ratio of some accelerations?

-physics noob

[CynthiaSMccleskey]

win, please..

[xxxcoolboyxxx]

ummm... the velocity this retard calculated is not the real velocity bcoz the velocity was not constant during the collision.

[gmartinz01]

Cal still won.

[ZzZzZzPaniic]

0:45-0:46 GeeZ!lol

[SGbranz]

but navy pilots feel that 3 g's for a longer peroid of time.....

[xxFLAVORBLASTEDxx]

Wow. And in NFL I bet they take twice that...

yeah pleas!

1:28 - 1:30 "three hundred and fourty five"

I would expect a physics teacher to properly word a number, it's "three hundred fourty five", there is no and. An 'and' represents a decimal point, so in actuality he is saying 300.45.

I know this seems like knit-picking, but that's like a food expert confusing a teaspoon and tablespoon measurement.

[WeAreYoMomma]

@itsMinuteMaid  Dont be an ass...

[m4g1c91]

There is an ''And''. ''Point'' is used to represent a decimal point, not ''And''.

[itsMinuteMaid]

WHAT?! No, you don't say 'point'. For example, when you say, 'two hundred thirty-three dollars AND forty-five cents' $233.45 (see hoe the and goes where the decimal goes). You wouldn't say 'two hundred and thirty-three dollars and forty-five cents', that would be $200.33.45. When do you say 'point'?

[titanwr]

@itsMinuteMaid you're confusing money with math - two different languages. For money you say "Three dollars AND forty five cents" because you are talking dollars and cents - two different values (dollars AND cents). For numbers in math, since the labels are the same - in this case feet per second squared, you have three hundred and an additional forty five. Same labels, therefore and is allowable - but in math context. True, you cant write it like that on a check, but its allowable.

[itsMinuteMaid]

[EDIT] 'How' (Typo)

[poon5000]

@ itsMInuteMaid

You are wrong. Actually "three hundred and forty five" is grammatically correct in proper English(Britain). Please don't correct a physics professor who has probably studied much longer than you.

[itsMinuteMaid]

He's a professor of physics, IN THE UNITED STATES. Even if what you say is true, that, that is the proper Britian wording, that is NOT the case here. Just as a word or phrase my be grammatically correct in Mexican Spanish, it may not be in Spain Spanish. Language evolves, just like everything else, and the wording for numbers has evolved to how I explained it. I wouldn't be suprised if YOU are wrong, and even in Britian, using 'and' in the middle of a whole number is incorrect.

[itsMinuteMaid]

Furthermore, in proving my point, you wouldn't say "fourty and nine", that would be incorrect, you would say (as we all do), "fourty nine". You do NOT say 'and', when stating a whole number, again, 'and', denotes a decimal point. I'm quite sure you're wrong, even about British English.

[poon5000]

@itsMinuteMaid What is the past tense of the verb "hang"?

It is hanged, not hung. There are many ways in which English grammar is counterintuitive. And as titanwr mentioned, math should not be confused with the proper way of writing checks.

Also your argument of British grammar being unacceptable in the USA is foolish. British English is the way the rest of the world is taught English, and is the world language.

If you are still not convinced, you can try to research it.

[8r9]

nice

[UniversalHere]

THAT KID GOT FUCKED UP!!!!

[heavygmoney73]

faggot, what boring as shit

[GregoryPunzo]

wow u just took something fun like football and turned it into a boring math problem

[wriglyextra]

nice

[chuckifubuck]

ABOUT 10.78 G's....

[GBooneoh]

We talk about sport too!!

Are you tired of people always trying to sell you shit? So am I. Download Lil Wayne the Rebirth FREE, FULL Album. @ THRILLA . NET - board, duh! I received 1 of the 500 copys that was accidently shipped early.... opps!!!

[Lazie4life]

-.-

[yooray]

good one!

[mtown78]

pause at 3:28 - ball broke the plane

[GroovyVideo2]

Dahlberg uses a Mac --

[eatsumkandy]

how is that a touchdown???

[flynnyboi10]

he got his leg in-look at the pylon

[lilwebbie85]

now calculate how much sperm in my tip.LOL

[mtown78]

now calculate how many neurons he lost in that hit.

[fdparis18]

that wasnt a touchdown he never went through the endzone and he didnt knock over the pylon either

[Differentiate11]

How can they call that a touchdown? What the hell?

[shiron236]

Why is American and Australian football called football? Ask rugby players because it came from rugby football. They're both modified versions of the sports, they're both high different thougj

[SenorBartos]

i dont get it neither

football like we say in europe they call soccer

and rugby they call footbal

american football =/= football

foot as in foot and ball as in ball

but they THROW the ball i dont see the foot in american football

weak americans

[campbellsoup99]

the ball used to be a foot long. thus football

[SenorBartos]

explains alot

thx :)

[SenorBartos]

excuse me mr. asshole

but that guy is swedish

unless u can speak swedish like he speaks english u have the right to remain silence everything u say can and will be used against u.

at least us european ppl are able to learn another language

aj da kunt lezen en vertalen zij nog een bitje nen mutn wije want tis de moeite nie eens

good

permanent brain damage does not worth a scholarship

[OracleofHope]

Apparently its too late for you.

[yhanieforever]

nice!

[Iwantedacoolname]

That's a lot of unnecessary calculations.

How hard was he hit? "VERY hard." Wasnt that easier?

[TheJapanChannelDcom]

Which other countries still use "feet"???

Is it just America that is still imperial??

[jmisiur]

lets go SCARLET KNIGHTS. MERRY CHRISTMAS ALL.

[sstrunks5555]

Go Bears :D

[tibiafun]

lol

[EddieJet16]

wow and he calculated all that shit? haha

[dacoolguy7]

that's basic calculus..

[Flinxster]

WOW

[KhyberBoy09]

this is NOT football.

football is what's played in Wembley stadium and Camp Nou

[gregory06]

Shut up. Two different sports are called different things in different areas of the world. Big fucking deal.

[EddieJet16]

no...that soccer...soccer is the one played with feet, football is this

[free533]

no, football can refer to many different sports depending on where you live

in Australia, football can mean AFL so in Australia we call NFL "Gridion" or just NFL.

in England football can mean Soccer

[syphmatic]

wow

[jamesjdm]

10.78 Gs is well within the realm that the human body can handle. Fighter pilots in say an F-16 routinely and for periods of 10-20 seconds hit 9Gs in ghigh speed tight turns. I played football through college and can tell you, it isn't always the impact that hurts...alot of times it is the hardness of the helmet hitting your hip bone or something like that, or getting stepped on by cleats! cool vid

[eddie12208]

His speed down the field shouldn't really factor in because it looks like he slowed down at the end there in order to get ready to catch the ball. There's no way he was going as fast as he was down the field when he turned to get the ball, turn back around to go for the goal, etc.

[eddie12208]

haha 1:30 -- gotta have the typical fake skeleton in a science setting.

[onehitquake]

were the audio?

[nitinopp]

This is high school physics. Fail

[koldmarv]

lll

[J337soorma]

That makes a lot of sense to me. I did the report on a roller coaster problem given to me by my physics professor. It was a lot of G'zzz..lol

[PLANBSKATER100]

Fake and Gay

[jamesjdm]

yes math is both fake and gay. you are right homophob

[atoz09333]

i reley liked this video it was really cool

[yankeecroc]

actually, the ball needs to break the plane, and it looked like it did.

[sohigh159]

just a little bit more ,but wait! dad physic need to use for proof the truth?!?!

[79821901]

this is not all true . his comin up with all these big numbers and saying that he took 10ft/s2 and shit wen with all the paddin the footballers are wearin it atleast took 50 % of the impact ! pussy stuff :P

[seu754e5rjdjf7]

A Cal professor would've done those calculations in his head.

[J337soorma]

It's better to do on the board sometimes.
