Real Word Problems From My Physics Book - PH17

[creativewriter1000]

1:44

creepy psychopathic stare

[Jguy365]

When I found out that Count Basie was black, I was surprised. (Not to be racist or anything.) I just didn't picture him as a black person.

[sethious1]

312 dislikes from people who lost a loved one do to this word problem

[xaouqinz]

lol I know exactly how you feel. Love the video

[velvetcat]

LMAO the other kid's face

[TheMrflutterguy]

My physic teacher showed this in class. Best teacher ever

[1devo6587]

OMG, I HAVE STUPID STORY PROBLEMS LIKE THIS AT SCHOOL ALL THE TIME

[MermaidKendall]

Eric…I thought you were in the 70's...

[huyked]

I guess he didn't want to see the light.

[pkemr4]

cool story bro

[jwkublick]

"before you drown". kinda reminds me of the Metalocalypse episode "DethDad". Picles says "Okay, i´ll stay out here and freze, and then go inside RIGTH before i freze to death". btw, nice video :D

[chrislongden4]

I once had a question on Doppler Shifts, where you compared the frequency of a train's whistle by standing directly behind and in front of the train. Of course, standing directly in front of the train results in death and therefore no frequency is observed.

[reksub10]

and ?

[flowerbower]

Does anyone else remember the spoof Q&A that 'went around the world' in the seventies and asked, "given an accurate barometer, how would you find out the height of your apartment block"? Among the many hilarious answers were: "use the barometer to bribe the janitor to measure it" and "drop the barometer from the top and time the fall".

Certain physics teachers should be shot on sight, and I say that as a physicist. No wonder the subject is in decline in the West.

[G3org3Master]

@flowerbower I also hate how we are not allowed computers and google and supercalculators to work out maths in tests... In the real world you would use your initiative and "cheat".

[flowerbower]

@G3org3Master Good physics teachers positively encourage 'back of the envelope' calculations and the consideration of 'Fermi problems'.

The book, 'Consider a Spherical Cow', was laughed at by engineers when it first appeared because they thought that details of construction were important. Physicists praised it because they realised that the details were - in a first approximation - unimportant: it is the principle that matters.

[gman21xx]

@G3org3Master in the real world the problems are a gazillion times more difficult. Not only are the "numbers" messy, but when doing calculations you have to worry about a million things in your algorithm. do you really want such a problem on a test?!

[G3org3Master]

@gman21xx Then at least don't call this book 'real world problems'! :p

And anyway your description of real world problems was ambiguous, could you please give an example of something a gazillion times more difficult?

[upinflamezzz]

I always thought related rates were the hardest problems I stumbled upon

[xxfm12xx]

And the point of that was????

[shamusparks]

Thats great!!!!

[HireWithUs]

why , istead of , not shoot your self ;-D

[HireWithUs]

why don' t you check at the e-bay if someone offers a brain ?

[bcpsleeperkid4]

I had a physics problem that went "Say you're an intergalactic space traveler trying to watch your weight. If you weigh 158 lbs on Earth, how much would you weigh on Mars?"

[SoraOokami]

I love it. haha Quite brilliant.

[PEZenfuego]

Awesome

[lopo2013]

i have the same speakers for my computer.

[Bobbrikolo]

1:35-2:37 this man looks very...weird x)

[Fargobreath]

Dear God, I can totally relate to this.

[globalarte]

This is hilarious ... so can you perceive refraction ?

[FataleChryses]

Wait, so what was the question asking, for you to sketch what the cup would look like? How the hell is that a physics question?? xF

[HazeGreyAndUnderway]

In the phucked up world of physics, everyone is right and everyone is wrong, and no one knows why the hell it matters.

[leirgauk]

wow, brandon was friends with keanu reeves ^^ wonder if theyre still friends, after keanus breakthrough and brandon's internet glory.

[CaseDL6]

haha... i square danced to this song once.

nicely done though :D

[RogJenSamBen]

Just wanna let you guys know that I am a high school physics teacher. I saw this video about 2 years ago and it is still my all-time favorite funny video on YouTube. You guys crack me up. Mainly cuz it is so true.

[jones3420012001]

Haha! you know the guys who wrote that problem were probably jokesters and would be loving it if they knew that someone thought their problem was weird enough to make a video of and put it on youtube :)

[damarei]

Awesome video!

[19jrags]

there is a simple pendulum on a massless string of length L with a mass of m hanging from a truck swinging back and forth when the car is at rest. what will happen if the truck starts to accelerate @ a rate of 5 m/s. sketch what it will do... the real question is why is there a pendulum hanging from a truck and where can i find massless strings?

[Toml420]

A fish is hanging from a scale in an elevator, the scale reads 5kg when the lift is stationary, what does it read when the lift accelerates upward at 3.2m/s^2?

A problem from one of my textbooks, lol

[fanbutton]

Gay as chit!

[BEASLAND000]

@fanbutton for some weird reason I agree with you...

i dont know why...

[samsalim100]

W T F MATE so what the answer??/

[Gastel]

@samsalim100 You have to go and try it for yourself!

[scorpioeye77]

dude...that was hilarious. Bravo

[duo3456]

lol did you drown?

[Nerfi]

"Ah, screw this" is exactly what I say whenever I start doing problems from my physics book.

[Bastable18]

shave ass

[robdux]

if im correct in my assumption it has to deal with refraction

[jamespat10]

Real WORLD problems.

[theyoungster2]

Lol.

[sorairo826]

i like the stare of the guy with glasses lol

[Iamallthatisman08]

This is kind of hilarious.

[dontdodrugs666]

LOLOLOLOLOLOLOLOLOLOLOLOL

[MrHacker3000]

what is true? i simply don't get it!

help please

[DollhouseBloodbath]

haha, this is great.

[libertylizzy]

now that's creative!

[kerridied]

This reminds me of a physics question we had where a squirrel on ice throws a stone at something else. Had us laughing for ages.

[chutsu]

nice touch!

[flamingfigures]

Usually the samples in my physics class involve blowing up small cuddly animals or shooting them out of a canon...

[thebuzzcjc]

I suppose this is some ludicrous example of water bending light reflected off an object as the last vision some emo douche would see before they almost drowned themselves in yet another pathetic bid for for attention. Nice vid BTW!

[thumphrey05]

there should be a "d" at the end of the word drown imo

[Sabohaque]

no. thats like saying, "you will inherited your title."

[doctaword]

I bet that's illegal in another country...

[omgthegamer]

I just had to come watch this video again now that I'm taking Physics. I'm doing my homework and I came across yet another absurd written problem about schools naming their mascots after mountain lions.

[FourthDimensionAnim]

Was this a problem in optics or what?? Great video.

[scout6686]

wow this is really good

[MorbidAngel4444]

AHAHA THIS MADE ME LAUGH SO HARD. thanks for the laugh dude xD

[davidrodgersNJ]

Major in communications. There's no physics, and you get to make movies, like this one.

[XxPushoverxX]

AHAHA. awesome video.

[KrimsonKrow]

My physics book was full of problems like this - only they all seemed to involve penguins in some way or another.

[Nowekian]

penguins aren't physics!! ...i like penguins.

[boredman443]

@Nowekian Penguins defy all physics.

[JodieinTX]

What the hell, weirdest problem ever. But I love the hilarity that ensued from the renactment

[Kazturkey]

"Before you drown" lol

[menelaoslyk]

And I thought greek teachers were nazis.

[Spanulator]

Haha good old refraction

[51918]

For some reason, I am unable to watch this. It says "an error has occurred, please try again later"

[mellissakatarina]

LOL

[jllaneshernandez]

hahahhahaaha this is very true these books always choose the craziest real life problems hahahha

[MrXevier]

Photoshop filters FTW. :p

[colacocala]

einstein said it the best "legalize it"

[soragirl792]

lol sometimes we focus and study things that quite frankly are...ridiculous. I mean C'mon!! lol

[Afr0Afr0]

This was the intro to a serious physics question i came across:

You are standing directly on top of your friends head who is directly standing on top of a cat...

[polarchucky]

then what did the sketch look like? and did he drown?

[elementhalgoddess94]

WTF? i dont think im going to even ask lol

[prancinglard2]

funny

[KingOfTheBritains]

this is a beautiful sentence.

[TheCritRocket]

QUIET YOU

[KingOfTheBritains]

bahah it was a response to someone.

[TheCritRocket]

i lold

[pokechatter]

wow.

[CutieReviews]

yay for geeks in zelda hoodies woooo

[intindse]

lolwat?

[anonrhea]

hahahahaah!

[pleiademaia]

Oh my gosh, this is ridiculous. :D Hilarious video, though.

[4anilem]

o.O

[WS6TALS1]

physics gives me nightmares----but organic chemistry was worse...all i could see every night when i would try to sleep would be C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-­C-C-C-C-C-C-C-C-C-C-C-C-C-C-C-­C-C-C.......but anywase awesome vid!

[libbern]

Both are foundations for our modern technology .I dont understand how people cant see the incredible things we can do with such knowledge... Anyway, the homework problems in that book is ridiculous:D Good video.

(gotta admit organic chemistry is boring as hell, but usefull)

[jaketubedeja]

LMFAO brilliant guys... tbh the music made it awsome :D

[sobeita]

On one of my assignments about the perception of gravity in an elevator, it said in the 8th or 9th problem that the elevator cable snapped and the elevator fell all the way to the bottom - and then said in the following problem that "the student repeated the experiment." "What was his/her observation?" "None - he/she is dead!"

[MrDeverill]

1:20 - he is thinking sick thoughts xD

[tadshackles]

I just emailed my physics professor from college and HOPEFULLY he can shed some light on this mystery!!!

Ill post again when he emails back.

[tadshackles]

I guess the idea of the question is to show how perception changes based on the situation. You may start out drawing very nicely then as air runs out you would become quick and erratic. Maybe? There must be a reason for this question...

[erikamavrich]

ahahahhaah, he keeps looking at the cup under the water 1:54 lolol

[Jeffoween]

haha that's funny

[First2Ki11]

HAHAHAHA that part was hilarious when the guy just kept staring at him while the water filled the tub ROFL

[hitbyabear]

cause of death: homework assignment.

[bokana911]

That's hillarious especially, since anyone who has take physics would know that when he sketches it from underwater he sees the paper and his sketch differently so he would be sketching what it would be like exactly above water.

[elgurudelascachas]

xDDD

[Ch3wza]

Unless he/she was horrible at sketching =)

[trumpicana]

What level Physics is it? Also...is it a light defraction problem? I'm curious because I would like to work it.

[Eachonset630]

High School Physics and yes it is defraction. Also it would be less dangerous to watch a straw bend when you stick it in water than doing this.

[HeliosTG]

It's refraction. Diffraction is totally different.

[lifeisworth]

y did these guys so this experiment,what were their intentionsss.

definitly the sketch would b different when u r under water and when u r above.Becaz light bents when it hits the surface of water.

[OnlyStupidUsernames]

the guy who fills the bath looks likethe nerdiest person i've ever seen

[1smax16]

keep it coming bitches call you are alll a bunch of sad fucks that actually care what i TYPE!!!!

HAHAHAHAHAHAHAHAHAHAHAHA

you all make me laugh

[1smax16]

omg here comes his retard friends lol this guy makes me laugh cuz him and his friends are so retarded

[RockzormyBoxer]

do u even know what retard means?xD

[1smax16]

definition of retarded: Delayed in development; Having mental retardation; Under the influence of alcohol.......

and you are an idiot

definition

idiot: a person of subnormal intelligence

HAHAHAHAHAHAHA you little bitch

[RockzormyBoxer]

um calm down xD

[TheONESassyLassy]

i'm working on my homework right now and came across this while looking for help (somehow...)

wonderful.

[AfterKnightShine]

"Ah, screw this!" haha, sounds just like me when I do my physics assignment!

[daniia27colors]

i love ur videos brandon

[VicariouslyCurious]

Is that necessary?

[RoseofBattle]

I love that Zelda sweater!

[SammySamff1]

fantastic

[iMoxxy]

LMAO, I just can't wait to take Physics!

[OneEyedJacker]

Ever hear of TIR? Total internal reflection. You would see the bottom of the soap dish mirrored above. It'd look like a flying saucer. Did you really have to lie in the bathtub to figure that out?

[Progo35]

LOL

[MattyRys]

haha i remember in ours last year there was a question 'james had a nightmare that he was locked inside a train. all he has with him is a bat and a ball. if he hits the ball with the bat against the carriage over and over, will there be enough momentum for him to move the train to safety?'

something along those lines.. don't know where to begin pointing out what's wrong with it haha

[sniper2073]

That was the single greatest thing I have ever seen.

[choidj]

Man I love that song... Anyone want to send it to me?

[colechiefcole]

Oh, I remember one. Something about a mystical warrior swinging his flail, and finding the centripetal force.

[colechiefcole]

Oh man, I remember laughing about how ridiculous the questions they would ask in my high school Physics class were. This video is great.

[theotherther1]

Too many projectiles and weights...Measure the train's mass as determined by speed and acceleration before it hits you.

I have no interest in math whatsoever. Finally, proof of how irrelevant it is! Teach me to do my taxes and then leave me the hell alone! XD

[Dynamics18]

math is amazing. it is used in games, predicting things, anlyzing graphs data, etc. it is a huge part of our world. Somebody has to know it, and the only way to find those people is to teach everyone math.

[theotherther1]

The world needs mathematicians. But I am not and can never be one-I've always found math extremely hard. I'm struggling with college algebra.

Most of the comments here are by resentful students who don't want to learn math.

[HXL056100]

then it's bc of your lack of basic. got to pay some visit to the tutor center if your college got 1 . and try to get in the morning shift since not many around at that time and you can get some 1 on1 tutor.

[theotherther1]

I'm trying. I go to Sylvan twice a week, study 2 hours a day, get help after class from the teacher, and have 2 different tutors who come to my house on separate days. But I still don't do well.

My mom's a shrink-no wonder she had me diagnosed with a "math disability."

[HXL056100]

ohohh. been there . done that . turn out , 2 much cram school would require 2 much homework. so instead of spending all that time with tutors + teacher, get together with the top 5 smartest student in your class and get into study group. most of the time learning from your friends tend to make more sense. and you got to try atlest 4h perday ... 2h can't do much thou. . 3h for homework alone and 1h for reading either the previous or the next chapter. if not, try to do that in summer.

[uhrrtax]

to make babies the whole world does not have to become pornstars :)

math is being thought to allow you to function in the world do understand that 1000 is more than 9.99 and so on so on

[xXChillStarXx]

xD

LOL

[bozcro4lyf]

A thought experiment lol.

[thebebopfan]

Now this could be one of the reasons why people dont finish all of there homework. Bobby: " Hey Dad could you help me with my homework? Hank:" Sure, what do you need help with? Bobby: " I am stuck on a word problem" Hank: " OK, let me see the problem. ok it says, " you lie on your back in a bathtub without any water, wait what? reads on yada yada. What the hell is this crap! Why would anyone even do have the crap in this book? Im going to go get Dale and the guys to kick your teachers creepy ass

[FlavorRed]

The ending is great!

[GrothVanDraktelshiem]

I have that Legend of Zelda Jacket! We have something in common!

[SpikeLee69101]

hahaha that was good

[cmswannaloveu2]

lol,omg, So realistic. I usually give up on the problems too. And yeah, physics question are so weird, I mean why the hell do you want to know certain things like this, lol.

[oxon09]

they have applications which are far beyond the physics that is involved.

[dance2910]

LOL, does it actually say "and before you drown."

[iseelc]

wow i have that book.

[wowsa0]

My favorite problem is: A girl asks you to push her on a swing. You wish to give her a fright by making her do a full loop the loop but do not wish to harm her. What velocity do you need to give her from her starting position to ensure that the rope remains tight all the way around, give your answer in terms of r (length of the rope) and g (acceleration due to gravity).

[jump4h]

rofl

my physics book was riddled with penguins.

really there must have been like 40 penguin problems.

[BusHitStudios]

I'm so cdumb that I would have to actually do what the question said in order to find out the answer.

[goedensnowflakes]

LAWL.

[marlin138]

Haha funny! My favorite math problem is when a farmer boy gets so bored that he starts counting the legs of his chickens and cows and you are given the total number of animals and the total number of legs and need to find out how many are chickens and how many are cows!

[cabutchei]

I know that one!! I have done it already,it's nice to do it.

[jennyinwaiting]

This is awesome :D

but nothing beats my favourite maths question, which had an equation modelling a guy's journey to school. the question being "how long does it take for him to get to school & what time does he get there?"

after a bit of confusion because we couldn't find any kind of sensible answer, we checked the answers and it turned out we were actually right in thinking that the answer was 'he never gets to school, he just gets infinitely closer to it, forever'

[dance2910]

wow

[managedmango]

well im in canada have the most water bitches

na im kidding we shud share.... actually it all amaricas fault

[ryno123321]

who do they think they are writing such dumb crap on a book

[polzowatel]

who do you think you are commenting such dumb comment on this video

[ryno123321]

fully defending the word problems

[polzowatel]

lmao it was actually really dumb problem

[knightsofsalvation]

This could not be more true. Physics problems from the books were always hysterical. The guys who write these books think they are the smartest mofo's on the planet. I quote this from a guy by the name of Giancoli, he has written numerous Physics books. "We use the term heat as if we know what we mean" Verbatim. Physics guys are such smart asses... so funny.

[justdreamingfilms]

oooh my god, i remember one question in my physics book......it was something along the lines of, "a duck on a scooter goes down the street..."

a duck? on a scooter? REALLY?

[foodfighternat]

Nice, but you used wasted that bath water which 3rd World countries could of used as drinking water.

Just kidding, i'm no enviromentalist.

Nice video :P

[eatabrownie]

I'm in a 3rd world country and guess what... WE DO HAVE WATER.

how cools that!

[enispdererste]

haha good job @ eatabrownie! :D

[eatabrownie]

whaaaat?

o.O
