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
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 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!
I barely understood anything from my Teacher at School. I learned everything effectively and more knowledgeable resources from Cognito. Literally saved my life.
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
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 💕
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.
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!
Can anybody solve this question? A 100g mass is suspended from a spring next to a vertical meter rule. The top of the spring is level with the 0.0cm mark. The bottom of the spring is level with the 27.2cm mark. The 100g mass is replaced with a 600g mass. The length of the spring is now 89.7 cm. The spring has not reached the limit of proportionality. The 600g mass is replaced with 200g mass. What is the length of the spring?
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.

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 😂😂

@@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
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 :/

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

Keep it on you are a good teacher bro!
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 was literally crying trying to understand this before. Thank you so much
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
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
I like the way that this video has no music
I wish ot had that
Thank you for your clear and concise explanation of Hooke's Law
I love your videos. Your calm voice is definitely better than my teacher's!

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 👍
Bruh these videos are a life saver thanks u are a better teacher than my actual science teachers
Bro my teacher's teaching is so bad, you are my savior.
I can't believe it can be this good
Wow, perfect video. You make it easier to understand. It should get more likes :) !
Thank you so much for the help and your affection to me in understanding the spring-constant!
Can you give us questions and formulas
1000 times better than my teacher 😅
Thank you for this five-minute...
Can you post an equation too? This lesson is very difficult for me
Thank you very much again! I'm studying for my Mock exams and this really summed the part where I had problems with!

Is it possible to calculate elastic limit?

Thank You So Much! Helped tremendously with a few doubts I had!
Taught me in 5 minutes than teacher for 80 minutes
I am struggling with the spring constant concept tysm for clearing it
Beautiful and brief explanation
👏 🙀 😯 😮
Thank you so much this video was so clearly explained perfect for homeschooling
u teach better then my teacher that has 45 minutes to teach your amazing
Is it ok if I use these videos for reference even though I'm in IGCSE?
thank you. taught me a lot. more vids pls.
Great video! This topic is very confusing so thanks very much!

thank you for the nice video. Very detailed and helpful information. Hope could help me in my test upcoming 💯👏🏻👍🏻
Man u saved me on the test ❤ keep going
How do we know that the deformation is Elastic Deformation, @4:59
Can you explain why acceleration is at its maximum when the spring is fully compressed? The velocity is 0 at this point.
for clarification this is when an object is dropped vertically onto a spring
Learned it from a proper source (Hooke's Law)
taught me better then my two lessns, real king
lessons*
before watching idk anything , after watching teacher would be the student and you explain to her.
always comes in clutch
Me after finding this video: peace at last
bro you made me cook in the exam thx
This helped me so much, thank u!!!
How did i not find this before my mock am so bad at physics but this really helps. Thank you so much.
I don't really get the stuff of F=ke, please help throw some more light there
finally a well made and easy one to understand, thx lots
this was amazing
U ARE REALLY THE BEST PERSON
U deserve more subs!!!!! This was very helpful!! Thank u☺️
Hi Siya, thank you for the comment and support!!
had come back all the way from as level to check out
Missed this lesson very helpful 😇

OMG thank you!! you saved me
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
Incorrect description of Elastic limit. Elastic limit may be after the limit of proportionality.
may god bless you!!!!!!!! your videos are very helpful, thank you!
Very useful! Thank you!
So deformation is just the extension right? My class is using n×deformation do describe stuff and it's confusing me a little bit.
thank you so much !!! this was an incredibly informative video!!! thank you
Love Hooke's Law!! Thanks for covering it :) Great video.
actually fr this time, i understood the whole unit in less that 10 minutes than in 90 minutes 💀💀
very well explained
2:02 what is extension
This was helpful, thank u so much
Thankyou very much it's superb useful
Can anybody solve this question?
A 100g mass is suspended from a spring next to a vertical meter rule. The top of the spring is level with the 0.0cm mark. The bottom of the spring is level with the 27.2cm mark. The 100g mass is replaced with a 600g mass. The length of the spring is now 89.7 cm. The spring has not reached the limit of proportionality.
The 600g mass is replaced with 200g mass. What is the length of the spring?
100:27.2
200:x
Cross multiply
Hopefully the physics test goes well ;)
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.
Watched so many videos on this topic still no one tells what is A inbspring equation
Thank you so much!!
