Shame to those 126 dislikes, this video was amazing, perfectly understood what I couldn't in a 2 hours class, Thanks for the amazing work.
it's now 203 shame to them
@@rudhraveena2638 its now 252 :(
now dislikes can't be seen 👍
@@muscle_enthusiast hahah
@@muscle_enthusiast I have the extension which makes it visible again, it's 285 now shame to them!
i dont understand why textbooks cant explain like this
Because that much paper would take millions of treessss 😅
Paper isn't human and paper doesn't have the same compassion required
lord, he ran at 28.8 kmph at the end
the motivation is real people
Ha LOL
Correct:)
Lmao
At last after four years, now i got the concept of instantaneous velocity. LOL
Seerat Fatima
Hahahahaha Really
Seerat Fatima 😆😆😆😆😂😂😁
@@cgme7076 Could you really be more of a rude asshole?
😁
@@flare439 Could you really be more of an ill-bred scoundrel?
Who is watching it in 2024
Ahhh this is so good! Have been scratching my head at my textbook for 10 minutes about this concept and your video totally cleared things up. Thank you!
Yess..
My teacher teach this in 45min but I was sleeping and not understand a single point but now I understand this only in 4min 😅😂
Newton walks into the room of squabbling physicists: He picks up the mic.. "Calculus bitches.." - epic mic drop
27kdon no strong language
@@deemalayed3779 yeahhh.. fuck strong language
@@deemalayed3779Man shut up and put on your big boy pants
LOL at "pretend" you're a physics student. Like who else would be researching these videos beside mainly physics students?
studying for the mcat
@@kenkaneki9138 Awesome, best of luck to you!
Design student 🥲
im 13 and im just learning random stuff for fun
Studying for the MDCAT
Wish I had a teacher Like him!😀😊
Bhai india me ese teacher nhi mil pate :(
So I'm guessing you finished college and have a job and stuff rn huh?
@@mohamedzafir8566 Yes sir, I do. And I did have a few cool teachers (Just a very few were cool, most were trash on a character level)
Cleared up some points I 've struggled with. I'm glad I donate to Kahn Academy.
It's KHAN Academy get it right goddamnit.
@@CorollaChronicles he donates.....Shut up
@@tahirmustafa2114 It's been a year. No need to say shut up.
@@CorollaChroniclesokay......
Besttt...never ever...since a long I scratched my head....but now a verrrryyy clearer concept...must watch it wid concentration...👍
My professor tries his best, but this man is the MVP. Thank you!
Could you explain the values of xsquared minus x on the graph and where they come from
BY FAR THE COOLEST & EASIEST EXPLANATION OF THIS CONCEPT I HAVE EVER SEEN! THANK YOU!!! I do have a qustion on the last kinematic formula used to find insant velocity. In this formula: "Vinstantaneous = Vi + at", does Vi stand for initial? And as for the second formula: "V^2 = Vinstant^2 + 2ax"; is this the same formula as the first with the "2" factored out from 1/2at or is the a different formula if "t" is not given. Either way, thank you so much!
Poor guy, no one has ever tried answering you for 7 years now, and sadly, I can't help you either...
it's been 7 years and no one has given u an answer... sadly I can't help
@@muscle_enthusiast that's exactly what I said lol
I am pretty sure Vi stands for V initial like the initial velocty
You may be graduated now or even settled in life .....
Test next tomorrow
Hopefully this'll be of help
SIR, WE DO REALLY APPRECIATE YOU.......YOU TAUGHT THE CONCEPTS WITHIN MINUTES THAT I HAVE BEEN STRUGGLING FOR HOURS
The exam is on Sunday, and I was absent when this lesson was explained, so I did not understand it, Thank you
THIS HELPED SO MUCH THANK YOU WHOEVER YOU ARE I LOVE YOU
Thanks for explaning
AMAZING....
THAT INSTANTANEOUS VELOCITY WAS A BIT CONFUSING FOR ME ...
NOW I AM ABLE TO UNDERSTAND THE CONCEPT
THANK U.....
WISH I HAD A TEACHER LIKE YOU.....
So easy this are just learn differentiation and integration
Finalllyyyyy i understood this
Just 4mins and it's crystal clear!!! 👍👍
your example is very perfect
thanks so much 🙏
0:51 sorry sir i want to ask if the instantaneous speed equals to the distance it have travelled. I mean that if its instantaneous velocity = 6m/s so will the distance of its instantaneous velocity = 6m.
Like, the first sec ( 1s) the instan veclocity = 6m/s => after 1s, the person on this video have travelled a distance = 6m, right ?
Good explanation thank u
yeah! really,
you nailed it!
omg I died watching this lol SO GOOD!
Thank you so much for that animated video! I was searching for videos and yours was the best one :)
Wow.
Concept is clear
3:14 Ah, the video that started it all...this clip encouraged me to jump into Calculus - 6 months later, I'm knee deep in Multivariable Calculus. Thank you, Khan Academy. ❤️
I just started learning calculus and it is so hard for me💀 Integration especially. They told us we had to learn calculus to solve these type of problems😭✋️
Superb.. I got the concept easily,,
That was very hard before.. Bt now wow... I got it... 😀😀
After watching 10 videos on youtube I've found a good video which would worth the time I had wasted.
Best academy ever!!!
This is amazing! I can't believe people also did this: "_______ wouldn't give up, so I'm not giving up either!"
awesome explanation
I wonder why TH-cam five minutes videos are often better than a whole physical class. Thanks man.
It's my fifth time and I am watching this cool shortly explained video! I am having a test tomorrow, so I wandered instead of reading my book and summarize this topic, why not look again at this video? Well! I did revise this whole bunch of complicated topic with just this video! Thanks a lot! 😜
Good luck!
His explanation was very clear. Loved this video
3:39 this very imp that when Instantneous velocity and average velocity is equal only when the velocity is constant or straight line graph
0:01 pretend? 😂😭
sir
u clear all my doubt
thnk u sooooo much
So ... the instantaneous velocity of an object can be *negative* during a specific moment on a time interval, despite the average velocity being positive???
4 minutes and 4 days....huge diff in this and my school
Thankss!! This videos helped me a lot.
Wow thank you!! This is amazing!!
ok, now this is epic
Simple & full of information !!
I will watch this video again and again :-))
Really loved it thanks sir ❤
in the calculation of the average velocity right at the beggining, it doesn't mention direction whatsoever, which is what differentiates velocity from speed, so shouldn't it be average speed instead?
timestamp: 1:23
Yeeeeaassss Khan Academy!!
The best Video at youtube on this topic
Thank u... For such lucid explanation.. 🙂
What a Cool and Awesome Video.
Great Job!
Very nice understanding skills .........plz tell instantaneous velocity in terms of circular motion
Asma Arshad radian/sec and m/s for linear,note circular motion has both of these, but centripetal force is causing the object to move circularly
How practically you explained!!! best explanation......i want u to be my teacher...
it was so difficult to understand this in class but this vid really help me
thank you the explanation was very help full
This is really great!!! Thank you.
FANTABULOUS!!!!!
This was so easy, why dont teachers teach us like this..
They din't teach us Calculus at school and began with this right away. Is it normal or it's the educational system here that's flawed?
+Ujjwal Kumar Jha Its very flawed. I tutor College students all the time. Those who come out of high school I would say are worse off than those who did not even had a high school math. I am not even allowed to say this but reasons is because the flaw educations teaches students memorization rather than understanding and can have students an illusion that thinks they understand when they dont.
I have no idea if they teach Calculus in High School. They probably just jump straight to the derivative rules right away.
Abdullah Noman taught the rules out of nowhere yes.
I never had a High School experience so I would not know.
I dont think education system is flawed , if u dont get something remember it & then someday u will build up upon that...: ) peace
But there's always a pattern to learn things effectively. You can't use differentiation in physics without even knowing what it is.
Yeah Indian 11th Physics is so stupid... You have finding deravitives everywhere in Physics but theres only one later chapter in Mathematics...
Ooh now I get it cool!
It's very helpful Thankyou 🌈🌈
Wow cool dude that was so simplified men kepp it up
hope that this guy make a private channel and explain all difficult concepts in some 5 minutes vids 🥰😍😍
Thanks.
If Newton just didn’t exist....
Thankyou!
THANK U HOOMAN
medical students need to know physics too!
Yeah
Thanks , so useful.
that star wars analogy is too accurate
WELL EXPLAIN..THANKS ALOT
Thank you
you nailed it! wow
What is difference between Instantaneous and non-uniform speed and velocity..??
Who else watching this the night before an exam
Me
Me😭
cracking video!
Finally watching after 7 years opps
I thought that they collaborated with minute physics
Balkaran LOOLL SAAMMEEE, I actually watched this video a few months ago on the khan academy app, and just now when I was looking for t I thought that minute physics had made it and was searching TH-cam because I forgot I had watched it on khan academy
BRO SAME!!
thought I'll never understand this lol... arigato gosaimas
Thankyou very musch.
How can a TH-cam video which is 4:37 seconds give more clarity than an online physics course that costs $2000. Failed system...
You are right bro
I'm gonna to teach this forr my students lol
you copycat
Thank you so much
who disliked?? idk, no ad, clean video.got everything
This was a life saver!
Hu, what about Leibniz?
Woww very nice
thank you
That was perfect.
These videos make one feel stupid like the illustration makes it so easy to understand that you start questioning why you didn't understand such 'easy' concepts for 4+ years.
really you are a great teacher
awesome !! very well explained :)
Much better than my teachers
I still can't grasp the idea of instantaneous velocity. How can a object or a particle have motion in just a moment. Particle needs to have a time period to do some motion, But in a moment it doesn't do any motion, how can it have any motion in a moment.
Nice motivation
#Fantaboulous sir just explain limit why it approaches to zero....
thank you so much !
