Thankyou for making such a wonderful website
great website mate
cheers
Got an exam tomorrow and I've been studying for weeks and only now discovered this channel. Hopefully I'll pass the exam and get an award for my grade.
i missed the online class but i found you which teaches better than my teacher. thank youu!!
I'm sure you r teacher is trying her best to teach u :) IDK just saying.
@@aotex3969 You think Aotex, you think
Wait for ur teacher to read this 😂😂
@@yuuvraajjain779 Haha lol
i know right
I have an assessment on Physics tomorrow and this video just cleared all my concepts which my teacher couldn't.
Taught me more in 5 min than my teacher in 45
real💀💀
Taught me more than my teacher in 3 lessons💀
Your absolutely right 😂
I still dont understand :/

My exam is after some hours and i was struggling after this video im finally feeling better thank you for helping me with your content you are amazing and dont stop uploading because you are helping me alot thanks
Me having a High level Physics exam tomorrow
This guy saving me as usual
same he's so good
My finals are in three hours, here I am
Hope you do well@@somebodythatyouusetoknow
did you pass
Thank you soo much. I was struggling to understand this topic, and the teacher doesnt help because he thinks that just because we are in triple science, we would be able to understand everything without explanations ;-;
Year 9 sucks.
not as much as yr 11 will bro
NO ONE CARES
@@AUSTIN06 ooh someone being salty
@@khushikhan4861 Facts :(
I'm sure yr 11 will suck more, but we can't appreciate yr 9 if we're not being taught. I was tested on physics with a higher paper without any helpful lessons ever since I started at my new school when before that, I hadn't been taught physics for 9 months, let alone anything anywhere near as advanced as what came up in the test. Now these tests, that I was told about the day before will determine whether I take triple science or not. So many teachers can take 2 minutes to check on the computer when the next test is or ask whether students understand what was taught and explain things again if necessary but chose not to as if they are only responsible for the students that succeed. People shouldn't forget how to do their jobs, jeopardise peoples' futures because of their laziness and blame it on the virus that everyone has to live with in some way. Period.
This channel teaches me more than someone who dedicates an hour of their day just to teach this one topic, but this video teaches me in 5 minutes! 5 MINUTES, you deserve WAYYYYYYYYYYYYYY more subscribers, you don't know how many people you are saving, you gained one subscriber
Keep it on you are a good teacher bro!
Wow, perfect video. You make it easier to understand. It should get more likes :) !
thank youuuu!! im doing A level phy and needed some revision on this topic, thanks again! :)
I have a test on monday and trust me this video is so beneficial, i was having a rough time understanding spring constant and you explained it so much better than my teacher in just 5 minutes!
Mee too lol
Who else has problems with a boring physics teacher raise your hand ✋

If you go down to the actual spring material, it is in fact a very thin long metal rod, wound into a coil form. If you observe closely what movement a spring is undertaking during compression or stretching you will observe that the this action is actually the bar twisting of equal amount throughout its entire length.
I don't normally revise but I will be sure to come back to this channel
I love your videos. Your calm voice is definitely better than my teacher's!
Wierdo
@@AUSTIN06 tf r u just gonna be salty and toxic on comments? Go get a life.

@@AUSTIN06 tf?
@@AUSTIN06 yt?
Exactly what i wanted to learn and had doubts and you really really really helped me a lot bro thanks a lot you are the best ❤
I barely understood anything from my Teacher at School. I learned everything effectively and more knowledgeable resources from Cognito. Literally saved my life.
Hi
I was literally crying trying to understand this before. Thank you so much
Thank you very much again! I'm studying for my Mock exams and this really summed the part where I had problems with!
Keep up the great work!! :D
pooooooooooooooooooooooooooooooooooop

Bruh these videos are a life saver thanks u are a better teacher than my actual science teachers
your videos are so helpful, i love them thank you
Hey Riker thank you for the support 🙌
Thank you for your clear and concise explanation of Hooke's Law
I’d like to thank you a lot, your videos are very good for revision
Hey thank you for leaving us a comment! Really happy they’re helping you out! Good luck with all your work 🙌
I can't believe it can be this good
You teach so well
You explain everything well and that is useful to understand everything fully
Thanks M00nWalker, glad you're finding the videos helpful 👍
thx i have been watching your vedios since i was in grade6 and now i am ninth grade you are best teacher better than my teacher
I like the way that this video has no music
I wish ot had that
this channel is a blessing
Thank you so much!
This helped me so much, thank u!!!
Better explanation 🤪 then teachers , she does even tell abt this information 😭 and that's why I always had difficulty, but not now thanks ❤❤❤ Don't stop🛑 making videos 😊 I am here for your support 💕
Thank you for this five-minute...
Can you post an equation too? This lesson is very difficult for me
Thank you so much for the help and your affection to me in understanding the spring-constant!
Bro my teacher's teaching is so bad, you are my savior.
thank you so much for this! my exams are near and this was great for revision. truly thankyou!!!!
I LOVE HIS CONTENTS I JUST DISCOVERD IT AND I AM HAVING AN EXAM TMRW THANKS😃😃😉
thank you. taught me a lot. more vids pls.
Beautiful and brief explanation
👏 🙀 😯 😮
Is it ok if I use these videos for reference even though I'm in IGCSE?
I am having exam on a few hours and after your lectures i am well content that i will get a good score aa i understood it easily and because you showed it in picture format i can remember it for long time
Thanks a lot
Thank you so much!! You know my teacher is rapping at class and this vid saved my life TY!!
Great video! This topic is very confusing so thanks very much!
Is it possible to calculate elastic limit?
Thank You So Much! Helped tremendously with a few doubts I had!
U deserve more subs!!!!! This was very helpful!! Thank u☺️

thank you so much !!! this was an incredibly informative video!!! thank you
Hi conginto, i am in grade 8 and i have A physics exma coming up i am an igece student and your videos always helps me either its math or physics
I am struggling with the spring constant concept tysm for clearing it
Man u saved me on the test ❤ keep going
HELPED ME ALOT THANKS SO MUCH 🙌🏻❤️
ah thankyou soooo much 😭😭
Very useful! Thank you!
Taught me in 5 minutes than teacher for 80 minutes
Bloody bloody Legend!!!
When will you do Chemistry or Biology vidoes??
Hi Kuba thanks for the comment - we’ve got quite a few out already covering all the double science stuff. What were you after specifically?
@@Cognitoedu do you have videos about human impacts on the environment for bio?
@@Cognitoedu Can you please do a video on what ions are and isotopes?? BTW Ur videos are great, thank you
P.S. THIS IS CHEMISTRY
taught me better then my two lessns, real king
lessons*
thanks
You’re welcome!
u teach better then my teacher that has 45 minutes to teach your amazing
Correct me if I am wrong but elasticity is the tendency of an object to stop distorting force and steel is more elastic than spring then the phone will be more elastic than spring, otherwise thanks for the whole lecture it was really great!
Elasticity refers to an object's ability to return to its original shape after being deformed, not necessarily to stop distorting force. Steel is generally more elastic than rubber, and springs are designed to be elastic, showcasing this property. However, when comparing steel to a spring, it depends on the type of spring as steel can be used to make springs, and the choice of material and design influence the spring's elasticity. So, it's not accurate to broadly claim that steel is more elastic than a spring. If you have further questions or need clarification, feel free to ask!
Thankyou very much it's superb useful
Thank you so much this video was so clearly explained perfect for homeschooling
many thanks!
I don't really get the stuff of F=ke, please help throw some more light there
Incorrect description of Elastic limit. Elastic limit may be after the limit of proportionality.
do we multiply in hooks law like F = K*E or divide? btw i love your videos and you
teach better than my teacher!
multiply
multiply, unless you are solving for K or E
where there is no fraction symbol in the equation and its written together, u always multiply. this ofc depends if you want to rearrange or manupilate the eqaution but its multiply :)
very well explained
thank you so much
U are amaizingg!!!!!!
Learned it from a proper source (Hooke's Law)
So deformation is just the extension right? My class is using n×deformation do describe stuff and it's confusing me a little bit.
The Graph is incorrect because the y axis is the dependent axis and so the x axis should be Force and y axis Extension. Force should be proportional to Extension.
In this case the graph is right.
How did i not find this before my mock am so bad at physics but this really helps. Thank you so much.
so helpful thanks my g
2:02 what is extension
had come back all the way from as level to check out
i have an exam tomorrow! wish me luck it’s ab hooked law, gravity, forces n exc
very much thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
tysm
Thank you
before watching idk anything , after watching teacher would be the student and you explain to her.
7278D 12:29
brilliant
actually fr this time, i understood the whole unit in less that 10 minutes than in 90 minutes 💀💀
How do we know that the deformation is Elastic Deformation, @4:59
My teacher played this exact video in class when we learned it
