Physics: Waves and oscillations (1)

[masterobishankenobi]

Hold tight free lance teacher!

[sciencerocks1995]

Please ignore the comment from earlier as it was my sister trolling on my account. Nevertheless, i respect what you have done for students like myself.

[sciencerocks1995]

i love you :) <3

period flow chart lulz

Who's talking in the most literal sense? I was merely pointing out that to insult someone you should at least do it with grammatical accuracy otherwise your opinion looks invalid. I retract my original comment I just thought that physically showing what horizontal meant was a bit 'pre-school' in a physics class and through the USA sounding accent it seemed fair to assume the students were morons and he was doing it for their genuine benifit giving the general educational standard there.

[ViralWeed]

:) you look like Alan from Two and a half man, that is great :)

[brighteyes715]

he makes me want a chalk board so bad

[marekday]

does anyone know how to calculate this 2. An elastic cord is 65 cm when a weight of 75 N hangs from it but is 85 cm long when a weight 180 N hangs from it. What is the “spring” constant k of this elastic cord?

would be really helpful, thanks

[ijeleo92]

I want to give you a hug so badly evertime one of your videos helps me understand physics. You're up to about 1,000 hugs:)

[piyushanly]

you probably will escalate my physics grade from an F to atleast a C

thanks again!

[numbsock1]

@piyushanly I have seen many people screw up in Physics for one reason: They over complicate. Physics is really not that hard, unless you're learning about the fabric of space time and whatnot. Assuming you're in high school, when you see a problem that seems convoluted, just calm down and don't make it seem like some Stephen Hawking type deal. It's not. I used to make this mistake and when I stopped (physics yoga haha) I improved my grade from a D+ to an A- in a matter of weeks.

Not only students should watch these videos. Most of the college professors must watch these videos too; so that they can learn how to teach. People like you are a true blessing to this world. I don't want to meet Kobe, MJ, DWade, but I wish I could meet you. No joke. You're such a positive inspiration.

[Battlenub74]

Argh i wanna pay u but im under 18

! next year i shall pay!

[HiiMDiZLeXiiK]

people like you are great, helping people learn for nothing. thank you very much!

[MilitantBlackGuy1]

00:48, you really needed to show what horizontally meant?

[foeasy16]

@MilitantBlackGuy1 stfu all he needs is a bitch like you tellin him how to teach

[MilitantBlackGuy1]

@foeasy16 Well if all he needs is that, then I'm glad I can be of service, learn how to speak you moron.

[bluefurryfood]

@MilitantBlackGuy1 He's typing, not speaking.

[MilitantBlackGuy1]

@bluefurryfood Although I did mean 'type', speaking can include typing or conveying yourself through written words.

[Iwantacookie2010]

@MilitantBlackGuy1 In the most literal sense, no, which was the exact same thing you were doing with foeasy16. I just found it funny that you were correcting someone's "speaking ability" when it really wasn't the relevant issue - e.g. you being a "bitch" about someone's video.

[arun4love1]

very helpful video

[Sharl360]

This man is a wiz!!!!!!!! over 1,800 videos of pure teaching.......

[adamigoswpl]

WOW. Nice movie. i rather to learn physics in Enlish than in my native language(Polish) Americans explain things much easier that Poles :) When do you learn that in US?

[Seracinfinity]

Much respect, you're very good at teaching.

Thanks for these videos.

[kruset11]

slow but thorough

good work

[Rowaaib]

I didn't think people still used chalkboards.

THANK YOU!

[fashiongurus1]

thank you

[drrojas]

WAAAAAAY better than Khan Academy!!! Waaaaay better!!!! :)

[miruljonas]

thanks a lot Lance...hehe,,

one of your students in Malaysia..

[TheBhagyashree1]

these videos are ausum ...

thankyou sir !!

[qcon81]

Excellent teacher!!!!!

[elitecanadian]

You are amazing! I hope you don't mind if I use a tad bit of your video as part of my physics project vid.

[smilebot1]

OMG DUDE YOU ARE AMAZING! i can NEVER pay attention in class and yet for some reason i can listen and actually understand n remember what you are saying!!

YOU ARE A BRILLIANT TEACHER!!!

[psakshayacomes]

awesome..........hope u r ma physics sir!!!

[psakshayacomes]

it was easy 2 understand thnks!!

[TimmysMummy]

your talking about points getting to the crest... what is the point? is it a molecule? a point in the atmosphere??? what does the ' point' consist of... sorry its a really basic question... but I need help :(

[Daniellexilux]

In england its called a peak not a crest.

[hkpopfan4lif3]

Oh man, I've been watching your Organic Chemistry videos for my ochem class. Now I've found physics! Awesome!

[9lade]

wtf mann this is not AS level

[gonganer]

you are amazing. please continue. 

[typicalmatter]

You should get a Nobel Prize whether for all the sciences or just for Peace. For promoting peace, encouraging education and taking the level of general education to a higher level by develoving conciousness about the sciences in a normal student. You explain everything very well. Its like atarting from zero, you leave us in the space. Thank you very much sir. You're my role model.

-One of your millions of students, from a distant part of the world.

@typicalmatter

Education comes from the latin educo meaning 'to develop or draw out from within'

This guy isn't educating anybody.

[virtus59]

@SadegoGG

ur an idiot!!!!

in english which you are speaking educate according to the webster dictionary is defined as "1. to train by formal instruction and supervised practice especially in a skill, trade, or profession, 2. to provide with information." I'll ask you how doesnt this guy educate? stop being an uneducated moron, and learn to speak english! If you need anymore education in the definition of words or there use in the english language; maybe he will make a video for you!

@virtus59

Look at the source of the word education. Webster made a mistake.

Study latin roots before getting into such a debate.

[rabia20086]

@typicalmatter i agree with you

[sarahvdwant]

For what grade is this?

[crystalidx]

@sarahvdwant grade 11 physics (but depends on your province or state)

[Ameliadams]

@crystalidx yup Malaysia is also in grade 11

[bluegumballs15]

I am currently in the midst of studying for my Physics midterm and your videos have been quite helpful. Thanks!

[dinx03]

thanks for this.. its really a big help for me as a physics teacher here in the Philippines.. although i am not a physics major, but i find physics interesting to teach to my students.. thank you very much.. God bless...

[Anti1gnorant]

I am on the 7th VIDEO RIGHT NOW..

im just going to comment on this and say that THIS DEFINATELY clears ur way of thinking about physics... u should definately go through it instead of reading the book

[LeBigKahuna]

@Anti1gnorant

amazing how much difference a good teacher can make

[imwithdumbhead]

@Anti1gnorant realy? definately? realy?

[Blu3Gh05t]

@imwithdumbhead yeah this guy makes things much easier trust me!
