Holy freaking crap, this guy has been uploading extremely high quality, extremely well made educational videos for a year... and only has 20k subs? What the hell is wrong with this platform??
ikr im shocked too
Almsot 90k subs now 👀
more than 90.1k now... lets check in a week.
He will gain subs, his videos are top quality
@Samir Nasiri Lmao
Can I just say...the way that this man soely is helping a whole generation. I appreicate these videos so much and their website is amazing
Thanks for this man. I've learnt more from this 5 minute video than from my 2 1-hour phhsics lesson in school
Ikr
I didn't understand what to do before I watched this channel. But now, I know what to do. So thank you for uploading useful videos.
THANK YOU SO MUCH.. THESE VIDEOS ARE SO HELPFUL,, JAZAK Allah!
Man i love this underated channel but barely any physics vids
Hey Aadam, thanks for the support! We're taking it easy with the physics uploads at the moment as we work on some behind-the-scenes stuff. However, come September we'll be releasing the physics videos at a much faster rate so everything will be covered well before your exams :)
@@Cognitoedu ❤
I wish i had access to teaching like this when i studied physics and maths at school
My science teacher recommended this channel and its pog
POGGERS
the cringe you have just generated is deeply painful
gravitational cringe energy has gone through my whole body, and cuz of that cringe energy, it made me make this cringe joke
wow i love this guys content, i managed to learn more from him than my science teacher! thats actually crazy bro im gonna pass my test for sure.
How did you do? Just curious, I have this test next week
@@smolPancakehamster passed with flying colours
The thought of doing year 10 work in year 8 just to get A+…
So helpful I'm pretty stuck on physics and I'm doing hw and this really help
what you know about Rowling down in the deep?
When your brain goes numb and you get a mental freeze
who’s here doing revision
nice vid man! keep it up!
i was so stressed out because i did bad on a small physics test and they gave us gcse variant 2 paper to work out on this test... Tysm you prevented me from giving up on physics!
I absolutely love your videos u saved my life thank u soooo mich!
this is really helpful i really appreciate it 😁
I love how he explains things he’s it’s like having a tutor ❤
this platform has helped me so much.without it i dont know wht i would have done.i really appreciate it
this channel is growing so fast! when i started watching you , the subscriber count was 240k , well done!!
Amazing! thanks a lot
Lovely clearly animated vids
Bruh, thank you so much. I missed a lot of school (like 2-3 years) and this helps catch up
Thank you so much I already watched this video about 2 months ago I literally forgot everything from it but now when tomorrow is my exam I watched it again it helped me a lot thank you so much COGINTO❤ 🙏🏻 guys I hope for you guys and myself to get grade 9/7 in our exams pray for me ❤
ABSOLUTELY AWESOME
Thx big bro these videos are really helpfull
This really helped
Very helpful and easy to follow
Anyone else been set this in quarantine?
Yep
Yeah
yesh my g
thank u so much!!!!
very good info
He really did just say if you enjoyed it lol. Like do you really expect me EnjOy physics 2 weeks before my mocks?
‘Enjoy’ in the sense of preferring it to mashing your face against a textbook really
@@Cognitoedu True🤣😭
@cognito what a good sport!
How will he know about that
@@vijethakariappa it’s called a joke dude
this account is just amazing
Ikr
I was just wondering is there a schedule that the last video is meant to be up by? I’m in yr 10 atm and was wondering if it will be done before my GCSEs.
Hi Ishan thanks for the comment! Yes they’ll all be up ready for next year’s GCSEs :)
Amazing vids but only a little sub thank you for uploading this helpful vids
legend
Thank you
Thanks queen
Bro is literally carrying our science grades
that apple gone to the moon😂
first and foremost thanks for you videos igcse ,
secondly can you start past paper doing in igcse exdecel
Thanks
Thanks for the gift
I love your videos. They are very clear.
Thank you Geeth! Really appreciate it :)
You legend
the vid was but in our school, the 'gravity' or using gravity to find an answer we use 10. As in gravity = 10N. keep up the good work
9.8 is the more specific one but 10 works too
4 years ago, He did what modern teachers cant do.
Is the force of gravity the force of attraction between two objects? So why does the earth pulls us towards him but we don't pull the earth toward ourselfs?
Hi can you make GCSE examples questions for some topics?
Our new platform has looooooads :) - cognitoedu.org
So,in 4:20,its means that the gravitational potential energy use the enrgy to get back onto the earth?
Very good video except that Gravitational Potential Energy is not a property of the object, this is a very common misconception held by teachers and hence by students. It is hence not correct to say that the object has a GPE of xxxJ, it is the Earth and Object system that the energy is transferred to when work is done by raising the object up in a gravitational field. In short the the energy is transferred to the system not the object.
Is that useful to know in GCSE/IGCSE, or is that something as high level as electricity and magnetism being the same thing under special relativity?
Here for gravitational field strength we use 10 N/Kg.😞
That makes your calculations a little bit simpler!
Hello ! Remember me ? That biology test went smoothly ( too smoothly now that I think about it ) ! The results will come in August , do you why does it takes so long ? ? And now I am watching your videos because I am considering to join a class that will tech the whole physics curricula of secondary school in one year ( if that makes sense ) …
By the way , I forgot to say . The way you explain things are so clear ! As an eleven year old that took the IGCSE biology test ( me ) , I literally saved thousands of pounds because of you ! ( IGCSE tutors want big bucks for their works ) , and I want to say . When tutors use two hours to talk about one topic , you only require one or two videos !
Thank you for everything !
Also , what app do you use to make these animations ?
Ah thankyou, really glad the videos have been helping and that the test went well! That class sounds interesting, hope it goes well 👍
@@Cognitoedu 🤗🤗🤗 excuse me , but do you know why the test results take so long to come out ?
@@dr.theory7900 they take long because they have to mark hundreds of thousands of papers all around the world lol, and not only that they have to proof check and proof read all papers again and again cuz IGCSE is a big deal and no mistakes can be taken, hopefully you get full marks!
LMS check in😭❗️
wait so for earth the gravitational field strength is simply 9.8 right...
It can also be 10
thank
s cognito very cool
please give proper definitions for the terms like mass and weight fo=rom next time would be real useful
Mass is how much thing is in the object.
Weight is how heavy an object is.
Weight can be changed depending on the Mass and Acceleration due to gravity. So the weight is dependent on Mass.
Mass is processed through calculations to get the weight.
Weight can be different based upon your location. While your mass will stay the same regardless of the location (however mass of a human or animal may change if they lose fat from body, this would lead to their weight also decreasing).
Because
Weight = Mass × Acceleration due to gravity (Gravitational Field Strength)
@cognit is so informative 😭
what's an intrinsic property?
The thing that's in the object and not dependent on the location. Like Mass is the thing in the object and it doesn't change because of the location.
"When you do a physics paper" Me doing it in 2 days 👌😳
try in a few hours, it’s not like i’m stressing or anything 😳
just watched it and mine is in 20 mins
But sir I have a question. In o levels gravitational field strength is 10 but you refer to 9.8. What do u say we should use 9.8 or 10
We have to round of to the nearest whole number either way so it should be fine.
It’s so nice to watch during summer break
Lol I’m in yr 5 (grade 4) and I still luv this
I'm British too lol
Is this england thiyory
can an IGCSE students like me be helped from this
If it weren't for Cognito I'd probably fail my GCSES ngl
Every single person who comments is going over these as they are studying for their mocks
I mean i love your videos but i would like to point out that ‘gravitation’ is the force of attraction between any two bodies of the universe. Whereas ‘gravity’ is the attraction between earth and its objects. So basically ‘gravity’ is what earths gravitational force is called. I see students getting confused alot about these so i tried to explain in the best way I could. Feel free to look it up. Have a nice day😊
@Everywhere Physics hey im actually in 10th grade and our textbook said and i also checked it out in some other books from our library and found similar differences between the both so i said this.
@@annarose5883 grade? You in America?
Perhaps it's a regional difference.
I’m really frustrated cus I’m so bad at physics nd I’m learning Abt this nd it’s so hard omg
but why would you divide by 1000 i just dont rlly understand :(
The mass has to always be in kg
@@citruz3587 (in physics)

I mean to be honest, everyone in the comments is having their mocks or anything upper level and I am over here in 7th grade because my school is mad and burdening us up. Lol
I’m in 5th grade😢
@@smolPancakehamster dude sucks to be you...
Hi
Gravity always10 sir
Wow
Welp I did not do well in Physics paper 2
0:53 ayo😮
gravity isnt a force
i hate physics :(
