Hooke's Law - A Level Physics

This video introduces and explains Hooke's Law for A Level Physics.
Stretch a spring, or a piece of metal, and it gets longer. The relationship between the force applied to an object and the object's extension is explained in this video, along with a method of investigating the behaviour of materials to produce a force-extension graph. Hooke's Law experiments are a popular demonstration for teachers to do in classrooms.
Thanks for watching,
Lewis

[@dereni6259]

As a physics professor it was impeccable video,i appreciate you

[@Fatima-zf5ym]

After many videos, I can say that you are the best.. thank you!!

[@bibekdarjee2833]

I always come to this channel before I start any topic at college so I have strong concept of the topic

[@PhysicsOnline]

+Bibek Bardewa Good luck in your studies, the more you prepare for your lessons the more you get out of them.

[@thevanthithevanesan148]

+A Level Physics Online your videos are very helpful thank you :)

[@niharkaturi1410]

Thank you! This video explains everything so clearly!

[@keywordmcat2256]

wow you are an excellent teacher!

[@appleonion9132]

I am leaving this comment for my future self, I am currently grade 9, I will come back after few more years and I hope I become something at that time, I wish my future self some good luck!

[@PhysicsOnline]

Good luck future you

[@humanloll]

Thanks a million for this

[@schoolofscienceglobal]

Impressive!!

[@moleily9743]

Thank you

[@chriswesley594]

Another nice video - thanks. A question though. Why, for Hooke's Law only, it seems do we flip the graph so that the dependent variable (extension) is on the X axis, whereas usually, it would be the dependent variable on the Y axis.

[@rajaarinah429]

Hi. I want to ask the same
question.

[@eishadia2917]

So that when the gradient of the line is calculated, this will give you the value for the spring constant, k

[@kaym2043]

thank you

[@59second66]

thank u so muchhh

[@user-nd4tu4vi6d]

Thank you❤

[@justintaylor5305]

How does GPE - elastic potential energy result in Kinetic energy?

[@malevip]

Sir Ples make a bit longer videos...

[@mythorium8143]

Thnx :)

[@hananayman2023]

THANKS A LOT FOR THE EXPLICIT EXPLANATION,SIR😊
SO I DO HAVE A QUESTION THE QUESTION IS IF THE SPRING IS STIFFER WILL THE GRADIENT OF THE GRAPH BE ALSO STEEPER?

[@deepfry4735]

Stiffer means a steeper gradient.

[@jennykeeling747]

If the gradient (Spring constant) of the blue graph is higher than the green, then why does it represent the stiff material and not the looser one?

[@jennykeeling747]

does it mean a higher spring constant makes the material extend less?

[@knockknock3physics165]

@@jennykeeling747 Yes. If you have the same amount of force on two strings then the one with the higher spring constant will extend less

[@sidm2422]

@@jennykeeling747 Yes, because the spring constant is how many Newtons are required to extend the spring by 1m. Therefore a larger spring constant means the spring will extend less when the same force is applied.

[@MohammadKhan-ls9qw]

Can you please cover projectile motion, please?

[@PhysicsOnline]

+Talal Khan Filmed it this week, editing this weekend.

[@MohammadKhan-ls9qw]

+A Level Physics Online Thanks in advance!

You just saved a life. +1 Google Marks for you!

[@karlkuttup]

if find it very odd by its name when its not hooke"s law its newton"s law some guy messes with springs and yeah new set of the same principles

[@zainabfayyaz2683]

if you could help me with the paper 9702 42 2007 question 1 b part ii.

I'm in year 7 why am I watching this
Edit: To everyone commenting, im currently at the end of year 12

[@catalyzt7162]

now ur in year 8 :D

[@starlitez_]

@say hello yooo i totally forgor about this
Yet still dont know why i was here-

[@YesIlikebananasSo]

Year 11?

What are you doing in a level

[@petrabanjarnahor229]

Is there any quantum explenation to why things bend ??

[@ALevelPhysicsOnlineYear13]

+Petra Marbun There probably is one - but don't over complicate it. Just think of the particles in the material moving relative to one another.

[@petrabanjarnahor229]

A Level Physics Online Members Well I'm not very satisfied with that answer.
