An unbelievable play on an American Football field is the perfect backdrop for understanding crucial physics concepts. Michelle Buchanan goes play-by-play on the vectors, the scalars, and the glory of a downright scientific touchdown.
Lesson by Michelle Buchanan, animation by TED-Ed.
Thanks everyone for the feedback on the title. We edited it to distinguish between the two sports. Our bad!
Great, I'll never think of football the same way again.
In my math class, scalars and vectors was pretty much boring graphs + boring explanation...and repeat. This was creative and it helped me understand. Thanks Michelle & TEDEd!
This really helped
I like the part where they use some obscure subject I know nothing about to explain things I already know. =)
Thanks!
Useless knowledge: european edition
Lesson one: physics in a game which nobody understand in Europe
MORE PHYSICS! WE DEMAND MORE PHYSICS VIDEOS!
Well done!
Could they have made this less annoying.
The thumbnail does show an American football field, and the thumbnail is also kinda part of the title
The youtube part of ted has always had a basics kind of feel to it. Apart from maybe s couple of history ones. So i don't expect the same as ted talks. But these vids always have great analogies and graphics.
precisely
Not in the description...
I was hoping for less basic physics but good video for people new to kinematics
yeah,so who wins!
Will someone please explain to me why some mathematicians consider vectors and points identical when they are so clearly fundamentally different regardless of if they happen to have the same x and y elements!!!!
dear teacher's show this to the kids who say they will never need this math in life
"It's not about football, but *insert what it is about here*"
Unless I'm mistaken, American football fields are measured in yards even in Europe...
in america it is
I recommend Khan Academy for the first year of Physics and first two years of Maths. In particular sections on calculus, differential equations, linear algebra and the entire section on Physics. As long as you know that, you'll have a comfortable time concentrating on really learning instead of merely keeping up.
for a moment i read "Michelle Bachmann" ...
never mind...they edited the title before I saw it.
Just watched this for school
Everything can be broken down to numbers.
how so?
Lol, the title was changed just after I watched it
Canada also calls it soccer.
This does not incorporate the psychological, or physical part of the game making this play nether believable or unbelievable. It is nothing more than a mathematical prediction on how a play should go, and that is what a coach is for. Except they would have most likely incorporated those two things into the play.
"If it was titled "water polo physics" then it would be a misleading title." This is exactly what I mean. It is misleading, because it's not about football. It's about American football.
it is about football, if the video was titled "shade physics" one could assume that the video is about an are with no sun but the video is in reality about a shade of color but that does not mean the the title is misleading. If it was titled "water polo physics" then it would be a misleading title.
The main reason most Americans find that type of complaint to be ridiculously pedantic is because it's nothing more than a dialectical difference. It would be the same as us getting mad at Europeans for referring to french fries as "chips".
Not really. You could say if a large number of people have come here mistakenly then they have been mislead. It doesn't mean it was deliberately titled to be misleading, but evidently some people have been mislead by the prevalence of the term. People who click on a video titled Polo Physics might be shocked to find it's actually Water Polo Physics. A subject they would not have clicked.
how is it misleading?
My question...Is there a science that explains why the defense would line up a linebacker against the "best receiver"? Was the defensive coordinator drunk or maybe just went for a hotdog? :D
Who is the audience for this thing? The internet is not as unintelligent as the producers assumed.
Captions on 0:26 = Contractor in the mail porno safety this exact opposite match up that they want ..dafuq?
This isn't football... this is fucking hand egg.
never you worry your confused mind!
No, you're welcome to bitch about fries. Because they originated in Belgium where they were called 'frieten' and later in France 'pommes frites'. Both terms of course referring to the act of frying, so 'fries' makes sense.
In regards to Football, that's the worst possible choice, since it is obviously more based on rugby than on 'soccer'. How about 'scrimball' or 'scrimmage' which is something unique (as far as I know) to North American football. Or handegg, which is fine by me too... ;)
*freedom fries
Puts the whole world into perspective, doesn't it? =P
*imperial
every country in the world, bar america calls "soccer" football, or a word derived or at least looks/ sounds like football, so for the vast majority of people this video will look like a "soccer" vid, thumbnail doesn't help either.
Science. It's literally everywhere
He's English. See the first comment for elaboration.
A vector as a length, a direction AND a orientation. Just saying.
What do you mean, but?
Ah, I actually stopped watching the video after 30 seconds. But you're right, I have to apologize, the only question I have now is, why is this on TED? I learned all this when I was 15, not even kidding.
This is more like maths than physics.
1: GCSE level
2. Imperial is 'wrong'
3. This is not football
NFL is like slow rugby
XOXO
Ehm yeah, the football part put me off
Football is science !! Am never watching it again they are trying to teach me
But?
But we're not in the USA, are we?
You should name this game soccer.
Use the metric system and your life will be a lot easier.
Because it's not about football.
Australians often call it soccer.
American football*
Nice, but not with metric values.
İs this really a lesson
Haha that play was terrible. What quarterback would lob the ball in the air like that.
The football vs soccer debate is boring the heck out of me.
Handegg physics*
Didn't understand a thing....
misleading title. :(
wow so many dislikes! Probably all the brits...
the GTFO
..until the next commentator comes along...
so stingy
Thanks for ruining football
this is not football !!! it looks like rugby...
Wow that was entirely pointless. You should have renamed it "Basic Physics"...
Super boring.
Cringe
horrible defensive playcall
this is such a bad way to explain these concepts wtf
i expected football and not the awful american version
Gridiron is boring
I don't like football. Why does the vectors video have to be about something that is perceived as decidedly male? Please redo with a topic that is more universal and less detested. Football is one of the few sports they IQ test you before you start playing so colleges can track if you lose IQ points due to head injuries. Is TED promoting head injuries and brutality?
I hope my kid is never in your class. Ms R.
