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.

i learned more in 7 min here than in 3hrs in my physics course thanks
ikr? What magic is this?
True
exactly
So true
Same here🤣
This is the ultimate way to teach physics, with moving images. Most of us aren't capable to follow along a 2 hour long explanation of how this works without any visualization. With a proper illustrarion of the concept, a 6 min video was enough to save my ass from a test! Thank you so so much to everyone who contributes in Khan Academy.
Exactly.....they should understand that we want visualisation to understand physics😔.
This video is a gift from the God.
Allen Wang and the god is KhanAcademy

idk why should we spend money and effort in university and keep listening to old people that they dont know how to deliver the concept to us staying at home and watching this is just perfect to me thx i loved it all :)
Mind Freaks that's right, there should be possibility just to pay for exams. If someone have enough knowledge to pass exams, when they should have possibility to get diploma. Diplomas only shows what person have competence to do whats is waited on it. In old times people had to go to university to get information, these days smart people can get information easily at home.
Now we are staying at home :)

Thanks
@@mindaugaskazlauskas5530 Only half correct... it also shows a person had the powers of focus, dilligence, tenacity, and dicipline to complete something complex, organized, and challenging over an extended period of time without flaming out... Many people after cramming for exams on youtube would totally flame out over time...not retain information, and be horrible people to depend on when trying to forward your business.
I LITERALLY CLAPPED AFTER THIS. YOU GODSENT!!!!
Doing physics and still thinking there is a god???
@@jacobvandijk6525 that's not the point you edgy atheist
@@alieser7770 O, really? ;-)
@@jacobvandijk6525 unfortunately
@@jacobvandijk6525 How ya doin mate. Could you give an insight into how physics disproves the existence of a higher power? Thanks. If everything that begins to exist has a cause and the universe had a beginning, then the universe has a cause. This 'cause' must not have a cause as that would result in an infinite chain that would mean we would never have existed. Therefore, whatever this 'cause' is, we know that a) it is infinite and b)it is uncreated(meaning it has always existed; the concept of time as we know it does not exist for this being).
I would love to discuss this with you mate let me know if you want to hop on discord.
I would give you Nobel Teaching prize

Thanks
This was SO simple to understand.
one of the best tutorials i have ever watched .Great job!!!
Omg this was the best teaching I ever gone through in my life
Simple
Neat
Short period of time
Amazing
Thanks. That helped me to understand things where other videos failed:
The capacitor has 2 plates. The battery pushes electrons onto 1 of the plates until it's crammed with electrons & the battery can't push any more on.
Inserting a dielectric increases capacitance because
1) the electrons (in the dielectric's atoms) lean towards the positive plate of the capacitor
2) therefore, each atom in the dielectric becomes polarised = 1 side is negative & the other side is positive
3) near the positive plate, there are some dielectric atoms. The negative sides of these atoms cancels out some of the positive plates positive-ness
4) near the negative plate, there are some dielectric atoms. The positive sides of these atoms cancels out some of the negative charge on the negative plate
6) thus the negative plate becomes less negative
7) the battery is now able to push more electrons onto the negative plate - thus the capacity of the negative plate to hold electrons has increased
the satisfaction of having all the concepts cleared in just 6 mins is just undescribable ... for the 1st time, this concept got cleared... hats off to u sir😍🥰💯💗❤💝💗💓❤🔥💥🔥
I am blown away😯Is this how much simple, intersting and LOGICAL physics is?🥺omg, why teachers let us just mug up those sophisticated mathematical equations whn physics can be explained this way🥺🥺🥺❤️❤️❤️You are a gem I tell u. Thankyou🙏
you explained this better than all of my teachers combined.
What is the background music? It sounds awesome with your explanation!
There must be a noble teaching prize now a days (because I think many teachers who don't know how to teach have become teachers) and this guy, David, must be, along with sal, among the first ones to get it.
now this is some real skilled explanation!
thank you, David Santo Pietro.

Thanks
I've been studying this for 4 hours and needed a better way than just reading the textbook. I completely followed and I feel so much more refreshed. Thank you!
I like how fast you speak and the way you present the material, it's very easy to follow. Thank you.
Ooohhh bhai.. ULTIMATE !!! The real definition of TEACHING;)
Great explanation!
Amazing explanation! I had struggled with this concept and now I finally understand. Thank you so much, sir!
dude. what the fuck. I...UNDERSTAND PHYSICS?
+Thomas Nguyen hahaha :D
It’s a great video! Really cleared my confusions!
7 years later, you're still helping a lot of students. What's better news?
I spent hours trying to understand this but now I fully understand it in under 7 mins!!! Feels good man. Thank you for the awesome video :)
thank you. your work is greatly appreciated by those studying higher level physics. you are the silent hero....
Thank you! I thought this process into the ground and the one thing I was missing was that some of those charges were canceling, which explained everything. Rad vid!
I've been turning over the pages of my physics textbook since a week, until I was gifted with this VIDEO.
I actually learned the concept in 7mins which I was wondering about for whole week♥️♥️♥️
Absolutely wonderful conceptual explanation; these are so hard to find nowadays. Thank you so much.
