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.
@@AlchemyOtaku It actually went decently well, there were two papers and on Paper 2 the first few questions were on this topic and I got full marks for those questions. Will be revisiting this channel more often
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
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
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.
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.
I barely understood anything from my Teacher at School. I learned everything effectively and more knowledgeable resources from Cognito. Literally saved my life.
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!
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 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
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 💕
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!
I have a query : how force in force-extension graph is dependent on extension however It is an elastic graph and because of force there will be extension moreover slope of force as independent variable is equal to modulus of elasticity and by keeping force dependent it will change the concept.
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 :)

Thankyou for making such a wonderful website
great website mate
cheers
I have an assessment on Physics tomorrow and this video just cleared all my concepts which my teacher couldn't.
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

@@Giebachii what grade did you get if you dont mind
@@AlchemyOtaku I got a 79% overall, it's not horrible (I think) but it shows that I need to do more practical work in addition to my usual reviewing
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
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 :/
Ong
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

BRO I LOVE YOUU. I have a problem with phisics they can not let me go to the last class. Finally i understand something. GOD BLESS YOU.
I don't normally revise but I will be sure to come back to this channel

Hi
Keep it on you are a good teacher bro!
Wow, perfect video. You make it easier to understand. It should get more likes :) !
Who else has problems with a boring physics teacher raise your hand ✋

Meeeeee✋️🙋♂️🙋♂️
thank youuuu!! im doing A level phy and needed some revision on this topic, thanks again! :)
love you, sir. You saved my exams!! 🙏🙏

Mee too lol
I have a test the following week, you are a life saver
Bro my teacher's teaching is so bad, you are my savior.
I was literally crying trying to understand this before. Thank you so much
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?
Bruh these videos are a life saver thanks u are a better teacher than my actual science teachers
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 can't believe it can be this good
I can humbly award with Indian youtuber status, thats how good your teaching is.
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 ❤
this channel is a blessing
Thank you for your clear and concise explanation of Hooke's Law
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
@@thezword669 tf
I like the way that this video has no music
I wish ot had that
Same bro, the other videos are so annoying with unnecessary background music's and effects
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 👍
Thak you so much❤❤ . Tomorrow is my paper
Thanks man tommorow I have an exam Im doing O levels and this video has helped me out a lot and so have your other ones
Thank you so much!! You know my teacher is rapping at class and this vid saved my life TY!!

thank you. taught me a lot. more vids pls.
Thank you for this five-minute...
Can you post an equation too? This lesson is very difficult for me
Watch8ng in 1 volume and 27 mins left till exam 😭 , Im so good at physics but js dont understand this SHIT topic
Great man
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
Me after finding this video: peace at last
Thank You So Much! Helped tremendously with a few doubts I had!
Can you give us questions and formulas
I am struggling with the spring constant concept tysm for clearing it
this was amazing
Thank you!!!!
taught me better then my two lessns, real king
lessons*
Missed this lesson very helpful 😇
U deserve more subs!!!!! This was very helpful!! Thank u☺️
Hi Siya, thank you for the comment and support!!
finally a well made and easy one to understand, thx lots
U ARE REALLY THE BEST PERSON
Is it possible to calculate elastic limit?
Love Hooke's Law!! Thanks for covering it :) Great video.
How do we know that the deformation is Elastic Deformation, @4:59
15 mins till exam 😱😱😱
Wish me luck guys
bro you made me cook in the exam thx
thank you for the nice video. Very detailed and helpful information. Hope could help me in my test upcoming 💯👏🏻👍🏻
i have an exam tomorrow! wish me luck it’s ab hooked law, gravity, forces n exc
Your the best .🙏
OMG thank you!! you saved me
2:02 what is extension
Is it ok if I use these videos for reference even though I'm in IGCSE?
HELPED ME ALOT THANKS SO MUCH 🙌🏻❤️
had come back all the way from as level to check out
Thank you so much this video was so clearly explained perfect for homeschooling
thank you so much !!! this was an incredibly informative video!!! thank you
may god bless you!!!!!!!! your videos are very helpful, thank you!
Very useful! Thank you!
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

very well explained
Incorrect description of Elastic limit. Elastic limit may be after the limit of proportionality.
This was helpful, thank u so much
Learned it from a proper source (Hooke's Law)
I have a query : how force in force-extension graph is dependent on extension however It is an elastic graph and because of force there will be extension moreover slope of force as independent variable is equal to modulus of elasticity and by keeping force dependent it will change the concept.
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 :)
Thankyou very much it's superb useful
Ty 😭😭😭😭😭😭😭
I don't really get the stuff of F=ke, please help throw some more light there
