A-Level Maths: R4-06 [Forces: Pulley Example 1]

[lilykim]

Hello sir! I’m an international student who recently sat the CIE 9709 Mathematics in June 2021. I wanted to do the full A-level in a year and hence had to self-study most of the content by myself. Your videos have helped me immensely and I wanted to say thank you for the fabulous content you have provided😊 I managed to get full marks on P1 and mechanics and dropped two marks for stats (and a couple more in P3) which resulted in A*. You are a legend! I’m planning to follow your Further Maths videos as well to prepare for Y13:)))

thank you! so much clearer than how my teacher explained it.

Absolute legend behaviour. I've got my EOY paper tomorrow and you've just saved my ass. Far, far better of a teacher than my one in school.

[jortcruncher]

Clear and straight to the point, thank you so much!! :)

[htafcedits]

Top lad appreciate the help very fast yet simple teaching

[alihematti]

You’re an absolute legend mate. God bless

[yaqubuddin]

This seemed so much more difficult than I thought. Your a legend

[rory_john]

thank you so much, I never thought I'd understand pulley questions, but the way you explained it here is so simple and easy :)

Does it matter if its the other way round? Like can I put the 5kg side as acceleration moving up and 2kg side as acceleration moving down or is there a specific rule for this?

Thanks you very much, covered all bases I needed

2:58 Huh? I thought the UK and other English-speaking world uses midline dot as a decimal (4·2 ms^-2) (maybe formally as I noticed British journal like The Lancet uses midline dot as decimal), the non-English speaking world uses commas as a decimal (4, 2 ms^-1), and the dot at the bottom (4.2 ms^-2) as a decimal is an American thing.

[anshuiyakarki]

when do u know if u should used 9.81 or the value of acceleration ? is it like for weight u use mx 9.81 and for fnet, u use acceleration value?

[ISS]

why are both tensions equivalent when they have different masses?

[gwil]

is the acceleration the same for both particles?

[samul]

wouldnt the tension for b be a different value

definitely not here because I have a Stats & Mechs Mock in 9 hours hehe..
