I know everyone knows how good this guy teaches Distance and Displacement but for real that's a good Sheep drawing right there
Dang..
Better than mine :/
yes
yeah

Hello pieck historia🧸
To people who have confusion:-
Distance:- the total path covered by an object.
Displacement:- the shortest distance between the starting to the final position
Tank you so much men
Thank
And if any body travels with making a an angle to 40 degree east from south and 95 degree west then ,what will be displacement
Thanks you I was still confused on displacement
Thank you for that I was still confused when I rewatchd the video 😁
this is actually not even that hard, its just my teacher can't teach, and that makes it hard. Thanks Khan, really appreciate it when I need your help.
Same lol that’s why im here
fr once u understnad it it seems so easy but when u have a bad teacher it seems impossible
Now I can actually say that our teacher doesn't teach properly
I'm replying to you guys, ya'll know why now😂
This 4 minute video has taught me better than a 40 minutes period. Thank you a lot to whoever has just taught me!
@repentandbelieveinJesusChrist1Amen! Annd in looking up displacement right now too lol
I wasn't listening so this is now how I'm learning
SAME
Same
Lmao same
That might be the best quick drawn sheep I’ve ever seen
I learned more from this Than I ever learned at school
omg a monbebe
Normal people: listening
Me: amazed of his drawing skills
That sheep ain’t getting tired travelling
😛
You explain the concepts very well, easily understandable to all. Inspired by you i have started a you tube channel in hindi "foundation physics" and it is getting very good response. THANKS.
literally you gave me a concept and you know im now interested in it i didnt got my teachers half an hour lec but your 4 minute lec gave me an amazing concept..Great Thanks🤩
dude my teacher made it even harder 🤦♀️ thank you tho
you know when a content creator is GOOD they don't need to remind you to hit that like button I just do it
this was so helpful for my presentation , i really like this guy's teaching method
I literally was so confused about displacement with distance over Volume thank you so much for clearing that up!
literally this is the best. taught me more in js 4 mins than 1 whole week of physics class lol
OMG YES FINALLY I UNDERSTOOD THIS CONCEPT! THANK YOU
first of all ☝🏽 who made all of this 😩
Sal Khan
Sala chootiya sa pada rha h
Bro im so impressed at the sheep he walked 25km
I should’ve known this account 3 years ago 😭 ty khan you made so easier
Distant traveled basically indicates the amount of travelling distance, such as, "to get here to there, i travelled 4 km, so the distant traveled is 4km". On the other hand, there is straight shortcut to get here to there which is around 2 km, so ultimately, the displacement will be 2 km",,,,,, I guess🤔
why the hindi video has been deleted from the channel or hidden please reupload it
beautiful sheep 10/10 sheep.
Thanks Sal!!
Hi aileen!Si camille to HAHAHA baka madaanan mo lang 'to habang nanonood
Khan Acadamy is legendary
The sheep helped me learn
omg this is the only source I use for studying or improving my knowledge.. school doesn't teach anything !!!
Please help me with my Physics question. Here's the question: I just walked 8km, southeast, and then I walked 20km, south. And then finally, I walked 8km, southwest. What is my displacement from my starting point to my finishing point? : )
mark jackson the answer is 36 km coz your are continuously travelling south or south-cardinal
36km
the awesome dipwad he also mention southwest! I don't think so 36km is a right answer . Southwest means middle in west/south.
Did you find the correct answer?
When you go Southeast, it makes an isosceles right triangle (45-45-90). To find the legs you divide the hypotenuse by Sqrt(2) [the square root of 2].
The Easterly travel is canceled out by the Westerly travel. So the net displacement is:
(20 + (2 x 8 / Sqrt(2))) km = (20 + (8 x Sqrt(2)) km = 31.3137 km South
Tysmm for posting this vidd (I'm a grade 7 student)
Migs Lauron why does it matter what your grade is
@@meirsahney3467 well it's none of your buisness, he is here to post a comment, now go and study you moron.....
ok
Thank youuuu khan academy 💗💗🤍
My book is so hard to understand, but this helped
The sheep has travelled 25km
Thank you!This helped sooo much😄
really good explanation as always
tysmmmmmm
How does one measure the distance of a location from the initial position that a person is in if you don't have a GPS in you?
What app does this guy use...he has good penmanship
I learnt more in this than a 1hr physics class
Teaching better than my physics teacher
Bene Naidoo i promissssse
Lecture on maths std 9 algebraic expression
That was really helpful, thankyouuuu
Tysmmm! I understand now
why didn't i get my teacher explaining this sht for 2 hrs and i get it for a 4 mins vid?? ight im dropping out .
i finally got it thanks
Why is the chance in position sometimes negative? The video doesn't explain
THANKSSSS I'M LITERALLY CRYING BCS OF MY HOMEWORK 😭 ANYWAYS THANKSSSSSS
The narrator got a key part wrong. He said that if someone said sheep travelled 5km it would be valid. It wouldn't be valid. The sheep travelled 25km. Travelled means distance covered. The sheep covered a distance of 25km. It doesn't matter that it ended up only 5km from where it started; that part is only relevant regards its displacement.
How do you solve for triangles
Thank you so much
You help me so much during the confinament.
so if a person starts out at one point, walks around in a square and ends up back at the starting point, would the displacement be 0?
yes
Is this the only difinition you have for displacement Because I see the definition of (position , coordinates , displacement) To be , and to mean Not what one does to itself But what something else does to it What happens to you as a result of An action from something else , that inturn Changes your position From where you were , to where your are now (from where you were before) This is my definition of Distance , displacement , and position !!!
Thank you very much
Thank you so much!
Omg I UNDERSTAND NOW!!!! 🤭🤭 im so dumb thank you for this 😭😭😭😭
Stop scrolling through comments and focus
Thank u very muchh))
Hlo baby doll😘😘
let's all agree we came here before the teacher taught us how to find it
Yess I finally get itttt
Extremely nicely explained.
I know its y'all understand this but the "sheep" hahaha i liked it its cute
thank youuu for this 🥰
Thank you so much. This is really very helpful
Distance=25km
Displacement=5km
A man says, let's just take displacement. It's a shorter distance.
Distance: Am I a joke to you?
Thank you for help 😃
THANKKK YOUUUUU!!!
Thank u very much sir :)
I understand some things about it’s kind of easy
I have a question How Can we Get The Displacement if its only going in one direction
@@swarajkerala769 yes correct 👍
Aileen alam kong nanunuod ka HAHAHA kaya natin tong p6
I said the sheep traveled 5 km south but in total it traveled 25 km
Please help me a body travels 4m north and take a left turns of 3m in west what will be the displacement tell me right. now please
5m from the Pythagorean theorem. The direction can be found from
θ = arcsin(4/5) .
5m
ليش صارت 5
اي صدك ليش؟؟
Remas Yas ممكن لأنها تكمل الشكل
Thanks
In short, displacement is a shortcut distance 😂
BUT HOW DO YOU FIND THE DISPLACEMENT? HOW DO U KNOW ITS 5KM SOUTH ?
JellyKookie Displacement = change in position. In the example given, the sheep travelled a total of 25 km. That's the total length it travelled. However, the CHANGE in POSITION the sheep has done is only 5 km from where it ORIGINALLY is. Hope this helps! :)
displacement means shortcut. the sheep could have only traveled 5km to that position it ended her journey.
If you observed the second part of the distance travelled, is 5km South. You just use logic and correlated the data.
3 million subs...but the recent videos seem dead :/
3:09 Distance is the overall path and displacement is the shortest path?🤔
yes
Where south to east 5m ,east to North 7m and north to west 9m then what will be displacement
My head has done to go to physics
25 m east, 20 m west, 40 m west, 30 m east, 50 m west, and 35 m east. Helpp about this question:
He sounds like marksman
ah thx
1:03 The sheep travelled 25 km .
how do you know it's 5 km south
The reason why it's 5 km is because displacement is a straight line from the initial position (starting) and final position (ending)
So its like a bridge. It connects the begging point and end point.
Hope it helps!
Its south because displacement is measured from the start point to the end point
Imagine the figure to be rectangle. You can see that it makes one. So the since in a rectangle opposite sides are equal, you will that the opposite side will be 5.
I did not understand properly can you make a video with more explination
my teacher explained that in 50 minutes lol
What I am sure abt is that sheep lost so much weight
I only understand the distance...
Me too

Bestie 😎🤩
wow😍
looks like officer tenpenny from GTA San Andreas
Who is watching this in 2021
bro the crosshair
So at the end I could only understand the concept by a sheep s drawing lol
Stop reading chats.. Focus on the video..
Why did it became 5 kilometres south?
