Isn't that this video???

[@ArefinRishad]

Dude! I literally jumped from Your "All of Edexcel International Paper 1 - AS/A-level Physics" to "Mass On A Slope" to "Easy Vector Resolving Trick " Video to understand a single thing you said on your first video

[@diarrhea5944]

Thank you so much. I'm actually an IB student who realised i needed to come back and review some of the basic concepts of physics. I never knew the purpose of SIN and COS until now. Thank you so much !!

[@glxsyy.Yuko4]

I was homeschooled all my life, came to school just a month before gcses. This is literally saving me. Physics paper 1 on Wednesday wish me luck!
(Ps: love ur videos tysm!)

[@OC74.]

Good luck, I was taken out and homeschooled for one year for year 10

[@amrosama7656]

Top work mate continue 👍👍
Rly useful, I am very thankful

[@sreeharikaruna3]

Thanks mate, was having trouble in taking sin and cos.

[@Pxth2Paradise]

That resolving vectors trick ❤❤ Thank you sm 🎉

[@mohammadeisa6157]

i miss the a3 paper and pens :c, Great video thanks

BEST WIDEO.... THIS HELP ME WITH GSCE..... LOVE FROM PAKISTAN❤❤❤

[@THEEFOSA6480]

absolute LEGEND. Bro is the saviour of my exams.

[@rowan2093]

love the new video style

[@ArefinRishad]

sir, I would very much like to know , why did we use multiplication & division at different times?

[@OC74.]

5:27 now RS has finally worked its way into science.

6:40 Hi sir, why do u divide by cos 20 and not multiply ? how do u know when to divide?

[@pluto3747]

Learn soh cah toa
Way better than than this guy
Itll help you in maths aswell

[@mantosh56]

​​@@pluto3747I second this lol...doing it that way makes more sense and the method that guy in the vid explained is something only he can understand lol

[@Thiloka.G]

his method makes perfect sense lol

[@scooupa]

THANK YOU SO MUCH YOU JUST MADE IT SO EASY

[@a9qvi]

really helpful explanation 🫶🏻😍

[@EvilsIronicRiddance]

Thank you! What do we do though, about vectors starting from the same point, i.e a baseline?? (GCSE)

[@kaeez]

7:25 - The force is angled so the displacement should be in that direction as well but you mention that the displacement is going horizontally? How come?

[@kaeez]

@@ScienceShorts Yeah, but when connecting the initial and final points the shortest distance in the example you used is the vector which is marked by F? The object ends up somewhere along the line F so that's where the initial and final point is supposed to meet and not somewhere horizontally right?

[@ScienceShorts]

Displacement doesn't need to be in the same direction as the force. But when calculating work done it does - that's why we need to multiply by cos theta.

[@kaeez]

​ @ScienceShorts Yeah, makes sense. But still my question is how does the box move to the right when the force is applied from the top-right? It should move towards the top-right in real world right? That's what made it confusing for me.

[@christopheramazigo4691]

Is this way of working acceptable on the mark scheme. Anyways you've earnt a new sub

[@ScienceShorts]

Yes. You do not need to explain how you've resolved.

[@christopheramazigo4691]

thanks@@ScienceShorts

[@klassischclassicalmusic8472]

Is this also the case for IAL CIE?@@ScienceShorts

[@abcdefg-hv2ks]

😭😭 crying, thank you so much!!!

[@resi4soot]

ok but what do you do when u need to use TAN?

[@ScienceShorts]

When you want to find one component from another component - you don't get asked to do that ever in physics, apart from banked track/plane in circular motion (I cover than in that video).

[@EveLeong-d2h]

Hi Sir, would like to know why is it different when finding the resultant we used division and component we use multiplication?

[@EveLeong-d2h]

is it because when we know the value should be smaller so we are using the multiplication and if bigger than we use division to find the bigger value?

[@ScienceShorts]

Yep!

[@coffeeeeaddict]

I like lost focus then came back when he said the Bible 😂☠️

[@BhaberAlishah]

absolute legend

[@aeihou]

how do you know when to divide?

[@ScienceShorts]

Component to resultant.

[@Amara-i9x]

great video

[@armannazad]

how do we know when to divide and when to multiply?

[@ArefinRishad]

exactly my question , thats the part im not getting too, btw did you get it? After these months?

[@ayeshasiddiqui9552]

@@ArefinRishad Try using "Some People Have, Curly Brown Hair, Till Painted Black"
its a way to learn trig sin cos tan, makes it easier to solve

[@blackfrost834]

@@ArefinRishad When you are looking to find a component of the resultant, you know that the value you are looking for is going to be smaller than that of the resultant. That's when you multiply (since sin or cos are always going to be between zero and one, and multiplying by a number between zero and one is always going to give you a smaller result).
For example: If you take a number and multiply it by 0.5 it is going to become smaller.
The opposite applies when you try to find the resultant. You know that the result you are looking for is going to be bigger than the component, so you divide (because dividing by a number between zero and one will give you a bigger result).
For example: If you take a number and divide it by 0.5 it is going to become bigger.

Also provide some related questions please!

[@macknacks]

we about to write brooo

[@huzaifaaliasgar5648]

DAMN!!!

[@yuvzyy]

sin and cos are ratios between -1 and 1, not 0 and 1

[@ScienceShorts]

We never do obtuse angles in physics

[@yuvzyy]

@@ScienceShorts makes sense. but still, saying that cos and sin are between 0 and 1 may confuse some people. otherwise, keep up the great content sir
