CALM DOWN !!!! People from the future will get scared when they read your comment if you are shouting about like that. Poor future, I’ll protect you. The best tool in the era of the modern civilization, and this is how we use it? To scare the future peoplea? Bad monkey! Bad!
starting to watch this as my last video on the a level unit 1 mechanics and materials playlist... i cant thank you enough sir. i joined As levels a week ago ... really late i had no understanding of any sort of questions... i thought my life was a mistake (seriously) after watching this playlist i feel way more confident as im stitting for it this coming tuesday. god bless you sir. and kindly pray i did enough with you and your past paper videos to help me pass my exams. much love sir.
This is really useful thank you so much I remembered teachers didn’t explain they expect a lot from students but you will be always a successful teacher
Hi, I'm quite confused with how you create the proportionality equations. What determines It? Also, might I mention that I LOVE you videos! Absolute lifesaver!
To things are directly proportional if they are both dependent on each other and one of them is a variable which can change in value. For example the formula for kinetic energy is Ek=(1/2)*m*v^2 We know (1/2) is a fixed value so of course a constant and the mass of whatever your finding the kinetic energy of also must remain constant and the only thing that can change is velocity therefore Ek is directly proportional to v^2. Hope that makes sense.
HI mate, sorry didn't catch your name? I've been watching your videos tonight and found them very helpfull. I am no longer in academic study but just do physics for fun now, being 58 it's about all I can do, lol. I was wondering if you could help me out on a little problem I'm having. I want to shrink the sun down to 32 mile in diameter and make it 3000 miles away, but I cannot for the life of me remember how to calculate the change in brightness, I'm not sure if the inverse square law would be the one to use here. Is there any chance you could point me in the right direction please?
not sure if you're still interested in this but in the specification I follow, aqa, this comes under as the astrophysics module. He's a link to a slideshow I found slideplayer.com/slide/7727273/ here's the equation sheet we're provided as well, in case you want to look anything else up filestore.aqa.org.uk/resources/physics/AQA-7408-SDB.PDF
I think you must to look again over the lesson "Variation" in math! Direct , Invers proportion etc! After that will discover how useful I this explanation! It could safe a lot of time for you !

One of THE MOST HELPFUL VIDEOS YOU CAN HAVE IN ALEVEL PHYSICS.

This may seem rather random to say but his voice reminds me of Father Blackwood's voice from the netflix show: the chilling adventures of Sabrina
omg !!! that's why I always thought smth is up
This Brudda is so harddd only thing I struggled with in year 1
You are the greatest man alive
Thanks for doing the timestamps.
Not even in A levels and I'm in need of a video like this haha

I can't thank you enough as someone who's very bad in practicals

Just found your channel , great stuff! subscribed.
Do you know where can I find exact exam questions on this topic. Thanks

Hi "mate" I didn't catch your name either. Sod off and MIND YOUR OWN BUSINESS!!!
Jam Mari Moldez It was only a question... I don't get your point here?
I’d try not to put factorials in the video because it might confuse some people
amazing content, I thank you
God bless you ❤
If young modulus increases by a factor of 2 and cross-sectional area reduces by a factor 3, how force and extension/compression will be affected.
Very helpful thank you!
Fabulous 🎉
Is this topic good for IGCSE student??
1:44 How is the force divided by the extension equal to k factorial?
not sure if you still need to know but its just an exclamation mark lol

It could safe a lot of time for you !
I could sleep to his voice
I have.
Thank you Chris Hemsworth
surely the gradient should be ln(A) as this is the gradient function ???
haha no!
That's what i thought. If you use y=mx+c where "x" is your "x". Then ln(A) is your gradient
How can the gradient be a variable
@@emperorjimmu9941 15:46
@@DoctorGamerr It's arranged in a way such that it is set out more like y = c + mx.
so ln(y) is y
ln(d) is c
x is m
ln(A) is x
is this As or A2?
Both
Just general skills for across the whole spec As and A2
yea thanks. was just asking coz they didn't teach us this in school
@@neerajbojwani3613 nah same, they just kind of assume you know it
