Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

[@filippetrovic9823]

I think this is one of the best explanations I have ever seen, btw much better than listening to my physics teacher :D

[@themechanic132]

same dude!

[@InvincibleAirman]

It seems like my graduation from university pretty much depends on KZbin. Not sure if that's a good or a bad thing.

[@geico105]

It’s good that you have something you can rely on at all, but in case KZbin ever fails you, you might want to have other forms of resources as back up.

[@swnsar]

you gonna have the like more than you expected, because most of the people doing like you. unfortunately me too

[@stephensynchronicity5631]

Imagine what we did before KZbin

[@user-sq1kz3ow3k]

InvincibleAirman the same lol

[@yogitagoswami9286]

They teach you this in university!!! Here in India they teach us this in 11th grade.

[@diby1555]

I feel like ive wasted 2 years with tutors....this is so much better....

[@fromexoplanet21]

I've never seen someone explain something so easily and in a way that makes total complete logical sense....our teachers just write some equations without explaining what each of the symbols and numbers represent nor what their relationships are to one another...it is a waste of my time and my life...but you just managed to explain math in such an elegant way that I've never seen before, thank you💖 I basically have survived all these years just by watching KZbin videos...you guys are the best teachers I know, hats off to you💖💐

[@raghdaelraaie9335]

and I was hoping my university is the only place that sucks and treats us this way 🥲

[@douchizheng3086]

I want to thank KZbin and Khan Academy as well as many other knowledge provider like Khan Academy, many education videos are a lot better than what my teacher taught me, KZbin is a great platform to study, I hope more people can benefit from this platform, knowledge can be spread in a faster, more accurate, easier to understand way

[@TheEliteCoder]

Spent almost six figures in a prestigious university so that I can learn for free from KZbin. If this isn't a dystopia than I'm not sure what this is.

[@rubaiyatmehedi9337]

@Bruce Xu specially during this pandemic

[@gnosis33-real]

You you could say it's a Utopia because you could have just learned from you KZbin saved time and money and took a loan out for six figures, started a business and be set for life on the unlimited amount of free knowledge readily available at your finger tips...just saying. Depends on your frame of reference

[@rubaiyatmehedi9337]

@Lisa Simpson which grade are you at?

[@rubaiyatmehedi9337]

@Lisa Simpson no need to apologise for your English you're pretty good. And you definitely should check out the trigonometry playlist from Khan academy. These are pretty basic things and you probably should've had a decent idea about these basics of trig since you're in your first year of physics. It's true that it's never too late to learn something but it might affect your institutional grades mate. And good luck😉

[@rubaiyatmehedi9337]

@Lisa Simpson And I might as well suggest you to buy a book called 'University Physics' I bet you'll love it. Would clear out any misconceptions about general physics give you a deeper understanding of the concepts of physics.

[@ameennaseem8936]

one of the best explanations i have ever seen

[@googleearth.755]

kzbin.info/www/bejne/e5zGkqyIhZp8fbs get a real view of sinusoidal waves

[@Meow_yj]

The explanation is so clear and intuitive! I wish this channel gets more appreciation, it deserves it.

[@maniyerjokhio2013]

I'll be ever grateful to you for such comprehensive explanation . Really, i could understand this chaotic wave equation only by going through channel ...

[@simranjoharle4220]

This video makes that complicated equation look so elegant....thank you so much!

[@ritzrox4679]

My mind is literally blown, I was searching for a derivation or at least an explanation of the wave equation and you explained it in such a clear way linking every step to the next. I can’t thank you and khan academy enough for putting such amazingly simple explanations for everyone to understand

[@NaveenKumar-vj9sc]

I enjoyed every moment of the explanation. This kind of explanation, I was always expecting, when I ask someone to explain me about wave equation but never a satisfied answer i got so far and now i am very much impressed with the content of the video and the way it is explained. I will keep from now on, this as the base explanation, if would want to explain anyone on wave equation. I just want to give infinite like to this video.Thank you soooooooo much.

[@wesleymarquardt4708]

THIS WAS SO GREAT. I was so confused when I was given an explanation in class, but this made it so clear. I had some homework concerning this equation and I was totally freaking out, but this was such a life saver. I breezed through the questions after this so thank you Khan Academy!

[@abenaboateng650]

Wow so clear. Never fully understood where this equation came from but it makes so much sense from this video. Thanks!!

[@lakshmidevihs2787]

this was out of this world thanks a lot

[@HAWI-SO]

It is a smart idea to use such videos as a professor to facilitate the teaching learning process in class . The video surely can be used as additional learning material to make the concept more clear . It has a very good visual representation.

[@Slime5276]

Thank you so much! Your a life saver for University Physics students.

[@shmkrar1153]

I have been trying to understand this equation for a long time - I mean years - and I finally get it. Thank you! 😊 Thank you very much!

[@jayantnigam5912]

That's the reason why Khan academy's is so awesome the way they explain the things and makes you understand each and very "PARTICLE"...of the subject....i must say..., To core concepts build and dug deep inside your brain which is never gonna fade away...i just salute to you sir....this one of the best explanation i had ever understood from any one....hats off to you....👍👍🙇🙇👏👏

[@mxame]

Thank you for this cool explanation !

[@nastarankianersi104]

I watched this video to try to understand electromagnetic waves. I'm not sure if I had really understood the concept of waves in high school but I absolutely understood now! Thank you so much!

[@sharurethi7809]

Sir this is what I was searching for days.... Thank you so much ❤

[@fardinhossain5410]

holy moly! this tutor is amazing!

[@nataliabacic]

Thank you for explaining everything. Even the intro, where you define y(x,t), was very helpful.

Great Explanation Sir....

[@ahmedzarka3407]

The Best of The Best ... 👏👏👏👏👏

[@justanotherguy469]

This is just great! A total education via KZbin. Very well explained, and graphically displayed. If you could make the cursor just a little more pronounced, so my slow mind can follow it on screen, I would be very thankful. Thank you!

[@its_mohammedsaeed928]

Best explanation ever 👌 👏 👍 I tried so much to understand this weird thing and i think i got it now Thank U so much

[@GaneshReddy9]

This is the best video of wave equation I have ever seen thanks a lot

[@amatore6]

I'm a person without math who has for many years struggled to understand QM and especially the Wave Function. I wish I would have started with this video. From this video I now understand much better what a "function" is and does. I knew that sine and cosine had to be involved in the equation, but now I understand how. I would imagine the QM Wave Function is similar but with more than just x and t involved, such as p, and I know that it is "complex." My goal is to understand how the WF predicts the future state of the quantum particle. This video is a huge help, and I have watched many.

[@waseemakhtar8981]

Good way of explanation
