10 minute free video teaches better than a 2 hour lecture in a class I pay >$1k a semester for. No joke, if I didn't need a piece of paper to be an engineer, I would not be at University

"ONE THIRD SQUAREDbye" lmao i didnt see that coming

10 min of watching this video was more beneficial to me than paying attention to four hours of school lecture! You're great teacher and I actually >>learned

never has such gibberish made so much sense as swiftly.

physisist goes to the Jewellery store: yes, I'd like to buy a hollow hoop of mass just kidding, good video :)

Your E&M videos saved me last year. Now its this video for my dynamics class hahaha. Our prof just said we need to know parallel axis theorem for rotation in rigid bodies but didn't go into the details. This was perfectly explained. Thank you!!!!

Thank you so much! I'm just watching a bunch of videos before my physics midterm in an hour and this is brilliant. So thank you from a physics major :'D

Excelent video! I learn the concept now!!!!

Hailing from Jamaica... Finally got this theorem thing after just this 1 video. respect!

Thanks for the multiple examples, really helpful and much appreciated!

Really nice video, super concise and conveys all of the necessary information

Wow sir ...You're awesome...!!..Trying to understand this theorem the whole day....Finally understood this.....Thank you soo much.....Concepts explained in such a simple manner...Thank you again :) :)

Very clear - great job, you are a wonderful teacher.

Thank you so much! You made this very clear and easy to understand.

what all the lectures in my university failed to explain over the course of a year; you managed to explain to me in under 3 mins of the video hahaha. Pretty much sums up university.

This is excellent, very clear and helps with applications.

Heads up for the great vid. It was really helpful.

I have that same book! that helps 50% of the time this video 100% of the time

WOW that was really helpful!!!!!!! IU make things simpler! Thank you and great sound effects indeed!

Thanks so much. Very concise and helpful.

Thank you for doing what you do.

Very gd explanation. Thanks a lot sir

thank you for making quality videos like this

trap phone ringin

Thanks for the help. Greatly appreciated.

Wonderful explanation!

Why is it that paper and sharpie lectures are always the best?

great explanation 💫

That was VERY helpful, thank you!

Haha the sound effects at1:14 are incredible :P Also, great video, definitely earned a like from me!

Conceptual wise perfect l loved it !

Thank you. Could`t find any explanation for that in brazilian youtube channels. Very nice

Great video! Thank you Sir.

great vid! I wasn't getting it but now it's all clear!

thanks dude! totally helped!

u sir are awesome !!

amazing video! i just understood it!!!!!

thanks a lot.....im glad i found this video

very much simplified thank u so much sir

Thank you so much!

that helps a lot. thank you

Many thanks!

brilliant Video

Epic teaching video

What book did you refer to in the video?

u sir, just got subscribed!!!!

Great ..many thanks

What the fuck? Why can't the teachers explain it just like this, very simple. Fuck school where everyone is a teacher! Thank you sir.

Thanq 4 this video.,nd teacher gv expressions too...(chooo-choooo)

Cool! Simple. Thanks.

Holy crap, as soon as you said "Hula hoop spinning around a nail" it all clicked in my mind.

Which book did you refer

Nice explanation

if you were to solve for the moment of inertia about the edge of the diagram should the mass be 4kg instead of 8 kg because the radius would zero for the other 4kg?

thank u..... awesome explanation........ :)

Great thanks, that helped me a lot. awesome sound effects ;)

THANKS!

Didn't know Norm Macdonald taught physics. Great video.

Thanks from Bangladesh ! ! ! And from Canada as well (As I'm studying here currently and the TA's and Professors and shit, They better watch this videos and then come to class ! ! !

Awesome video, thank you bye

very helpful

what book have you used to study this?

My Pearson physics book just burst into flames.

What's the name of thw book?

Thank you Thank you Thank you!!!!

Thank you lasseviren1, Very Cool!

AWESOME!!!!!!!!

In the case of the last example, why is the I(cm) of the rod 1/12th M(Lsquared) and not M(Lsquared)?

That was awesome. It ended rather abruptly...

THANKS A LOT!!!!!!!!!!!!!!!!!!!!!!

Thankyou

Thanks

thanks

top quality sound effects included ;)

My PHD physics professor explained the parallel axis theorem in about 4 minutes.... usually 40% of the class drops and after that it's a low C average.

Oh my god. You, sir. Rule so much.

Solid

Sorry if I'm just being stupid (it's been a long day) but where you use I=(mL^2)/12 isn't L meant to be cubed not squared?

the sound effects tho. hahaha nice vid man

thats great.

Great

Shouldn't there be 2 terms with 1.5m squared in the first part b/c the com is 1.5m away from 2 of the sides?

really good expla.. BYE!

Why am I paying tuition fees for college? xD

thnk uuuuuuuuuuuuuuuuuuu

I'm fairly confident that if every math teacher cared and didn't get sick of their job because of unruly kids, a lot more of us would be ahead of china in terms of math knowledge right now.

1:05 "notes I go through the center of mass". very important sentence. I wanted to revers the object and count inertia from other end of object. calculation was wrong. What I had to do, was firs move the axis to the center of mass and then moves again the axis to the end of object. When I did differently, put entire distance in equation and square it, the calculus was wrong.

1/12 ML^2 because it is a rod rotating through cm. Can be derived through integrating R^2 dm or just memorize for rods

super helpful! thanks

"wooooow wooooooow woooow" withh hand actions best part @01.15

Thanks... but the sound effects were very interesting

I like the cut off at the end lol

I think there is a mistake on the I (mass moment of inertia) at the centroid,,,,it should have been I=(mr^2)/2

I hear ya, I didn't use the book at all this semester, makes me question if i should ever buy textbooks again -.-

my heart sank when i saw the book xD i just hate physics books, i study it online, but books make me feel so stupid :D

haha i heard it as "bye"

Why square the distances? Nobody explains it.

He definitely said "fuck" at the last second

wait how did you do tha---Bye

@hasben0 sorry, i posted the question before i even finished wathin the video.
