Re arranging equations for AS level

[Koba4329]

how would i Re arrange

D= AT^2 / 2 + Vi T

[giorgiog01]

thankyouu!!!

[mstiqify]

OMG I USE THE SAME PEN :D

[MrSucker321]

thnx for the simple method another method is reversing the component ie f = m.a we want a on its own, mass is being multiplied so we have to divide by mass on both sides of the equation

[makaronas202]

bad teacher.

[vburm]

this is not gcse/as level. for gcse, you are expected to be able to do this in equations where the subject appears on either side of the equals sign. as is more advanced still.

[TheHandsomeCrab]

1:27 1:51 "move diagonally" is misleading and basically false. You are inverting a multiplier, not crudely "moving" a term.

By the end of this video a student could be easily forgiven for thinking the solution is V^2 - U^2 - 2a = s , because after all why can't moving sideways be as good as "moving diagonally"?

[fizzicsorg]

@TheHandsomeCrab

Yes it is a fairly crude explanation and could be misunderstood, but I find few students do misunderstand. The video is aimed at those who have problems with algebra and who need to be able to rearrange simple equations; to make the explanation as straightforward as possible I have made some compromises.

[genericteen]

thankyou so much! i have been doing badly in physics for my first 3 weeks because i did not know these rules which now seem so simple! :)

[steffywok]

Are there really people taking A level physics that can't do this??? Seriously? I was taught this when I was in year 9 (13/14 years old), and I went to a failing comprehensive school!

[bigbeatz06]

Thanks for the tips, this has been plaguing me all my life!!!lol

[supazo]

wow you totally just made me get how to solve equations. Thank you so much!

[STJukes]

I learnt this in GCSE :p

[gangstaz001]

Ok im not going to study A Level physics

[johnwoog]

This really helped. Nice one :) x

[mixxmexx]

What kind of pen is he using? I want one..don't ask me why..

[kevfoda]

man.. if you were a chick id marry you..

thanks.. saved my life.

[steve0619]

this cannot be for AS level, if you cant do this, you wouldnt nearly of passed GCSE !

[DanielCAANT]

hey if my equation is

T= 2pie times by the square root of L over g

what's the equation if g is on its own?

[2000essendon]

g = (4)(pie^2)(l) / (T^2)

[alyemany]

I have an exam 2morrow!

And thank you very much, this vedio was very helpfull.

Thnks again!

[kilaaaaa]

i have an exam tomorrow!

[linkinfan07]

yeeer i doo aswell, this is actually pretty helpful lol

[WOWFPS]

Thanks, this will help in my exam just a week from now. before this i coudlnt re arrange any of the suvat equations. thanks!!

[ryanmarceagles]

this was great :D cheers

[jumziejumzjumz]

Thanks, very useful.

[BogMonkey53]

I'm in a first year physics course and rearranging equations gives me more trouble than anything else.

[nuttychick]

Thank you....

[thephysicsidiot]

Thanks. This is helpful

[liam1852]

thanks... i needed to know what the equation for 'u' was in suvat.. was a big help :)

[neuphin]

Thank you!

This really helps when rearranging equations

[OldSchoolSkill]

Thank you for showing how simple algebra is!

This is similar to the way my father explained it to me when I was a young boy. After a little practice, I never forgot it.

I find it curious how modern schools, especially here in the USA make math so incomprehensible.

Does anyone here have an idea why that is so?

In the meantime, THANKS again!

Elegant, simple, Splendid!

[AurangzebQuetta]

i was 11 when this concept was taught to me..im from pakistan Asia

[dougalstevenson]

Your mom goes to Pakistan Asia

[teachmemagic2]

@AurangzebQuetta whats with the random info?

[aaadddaaammm777]

ok lets say our initial equation is a = f/m, now from THAT equation how do you solve for m? by moving the f to the acceleration side...i have a harder equation and i need to move the nominater of a fraction to the other side to solve for the denominator...is that even possible or no

[ExamFox]

@aaadddaaammm777 You should check out our website ExamFox? We've got some really experienced online tutors who can explain those kind of problems and the first lesson is totally free.

[Rebellion192]

I'm doing A2 physics but its always good to refresh your memory of the basics :)

very helpful, thanks

[stephenhockley]

very helpful. cheers.

[Oggsh]

Clearly explained... thanks

[kirbymkiiFTW]

Just started physics, was strugling in re arranging equations. This helped, a lot!

[nepalihercules]

lol in asian countries they learn these stuff in like when they're 12 yrs old. and i'm not lying.

i'm doing A level maths here in Uk and i find it so simple. i just got my resutls c1 99 c2 98 s1 99

p.s. i'm from nepal (its in asia) and i had just passed my high school from there so i'm no maths teacher

[BoxChalk]

simple answer for that...they've got a different curriculum

[nepalihercules]

its cuz what we learn here (UK) in A level maths we learn in year 8 (equivalent of year 9 of UK) in Nepal. and people here r just lazy and don't have to study a lot.

we used to have like 8 different courses running at the same time each with atleast 4 module where here we've just got like 4 courses max with 6 module each.

[jayanath05]

this is more like OL not AS.. but this isnt too hard even for that :)

(not being an ass) u seem to explain this very clearly ^^

[tuft125]

u just saved my ass in my physics exam THANKYOU SO MUCH!!!

[neversaydie1990]

ok

thanks man

[RoyBolinggoing]

This is very useful - thanks

[BB992]

AS? thts GCSE. only there r AS formulas, good for ppl hu cant rearrange tho :-D

[ZombieFashion]

Thanks. :]

Someone got me confused earlier and now I remember it correctly again! Thanks!

[5907cars]

thank you sir

if only my teachers were as helpful as you are.

[GoldZee]

I had to sign in to give you a comment. LOL! Thank YOUuuuuu...... it helped alot.

[ArcaneInquisitor]

The explanations are very clear an concise. But who is this aimed at? Where I am from "AS level" is not a commonly used phrase.

I ask because I assumed "AS" was an advanced level but I can't imagine how anyone can pass a grade 9 or 10 math course without being able to do this? No offense intended.

[fizzicsorg]

The term relates to the British education system and AS is at about 9th or 10th grade. It is also aimed as a catch up to those who meet the requirement in Physics and have forgotten earlier Maths.

[EddieandSophieViney]

@fizzicsorg... I am an adult returning to study, I AM doing physics and I HAVE forgotten most of my basic maths skills I had that exact formulae and was trying to remember how to transpose it... its all coming back to me now... thank you so much

[fizzicsorg]

@EddieandSophieViney Good to be of some help. I hope you enjoy your study. You may find the website at fizzics.co.uk of some use. Roger at fizzicsorg.

[BB992]

we do the english education. its the first part of the A level. we do our own version of the IB. in the year before last we do the AS exam. in the final year at school we do the A2 exam. its the british educational system.

[DuressRap]

@ArcaneInquisitor i agree with you but ive got to say that im doing AS physics and im having to learn how to do this, i got a A in my gcse maths but i couldnt do this .. before AS most the marks come from the shapes questions and as i was up to scratch with my shapes i could easy pass with a A without being able to do this .. i guess because it is thought of everyone to be able to do rearranging they didnt put many/any questions in the gcse so i didnt bother learning it (which i now regret)

[airmysteries]

thank you lots completeley forget how to rearrange equations

[WilmaProductions]

THANKYOU!

My physics teacher didn't explain quite as well as you hehe

[jam0n3]

It shows the internet isnt totally useless, that helped, thanks!

[omgalexis]

Thank you so much this really helped ! c:

[StarzGirl26]

Wow, that has totally just really helped me!!!!

:D Thanks!

[kingjoebooboo]

I have my first AS modular exam on tuesday, and this has really helped. Thanks!

Its so hard to forget the basics when learning so much. So its nice to see there's help on you tube.

[popping01]

very good helped alot but ur voice sounds like you should of stared in starwars as a gedi lol that was a compliment lol

[fizzicsorg]

Thanks. I will take that as a compliment, although I have had better!

[92GH]

I'm currently studying AS levels in

Maths, Physics, Biology & History.

I'm hoping for at least BBBC

[tinlee]

So this is an equation i have and is the rearraging i have done correct?

& = Delta

E = mc&Q

c = E/m&Q

Thanks for any help :)

[TheScientist15]

Very good!

Impressed

:)

[jawadkho]

Btw I have T=1.13s s=90cm  u=0 is that the right equation of motion I am using?

[fizzicsorg]

Yes, don't forget to put the distance units into metres, so a = 0.9/0.64 = 1.4 metres per second squared

[jawadkho]

I've got a equation for motion s=ut+1/2At^2

I want A to be the subject would this be right->[s-ut]/[1/2t^2]=a

[fizzicsorg]

Yes that is correct.

[jawadkho]

thanks

[Ransacked92]

Wow not bad indeed. In fact this tutorial is EXCELLENT. It has made everything to do with algebra seem a lot easier for me.

[dannyboilike]

thanks for the tutorial, saved my homework

[mightyhealthy360]

what does U stand for displacement? S is time? why do theses mf's always change stuff around?

[MrOmniscient]

U is usually used for initial velocity. S is displacement on the british syllabus. They change it around to confuse us... because they can.

[fizzicsorg]

U is the initial or starting velocity and S is distance, t is time. It's not logical but these are the commonly used symbols.

[Mobixpl]

I need a website that helps to rearrange a formulae with more than 1 letter on each side;/

[MrOmniscient]

If the letters are different, it is very unlikely that you can work out either of them from a single equation. And rearranging is hard to explain in text... if you want to send some examples somehow I can sort them out and explain the steps, but I cant really type up a general rule.

[halllorr]

ur a real good teacher :D

but can you put some more stuff on like....the atomic structure and prbing the nucleus. i always get stuck on writting decay equation

thnkz x

[fizzicsorg]

There's a bit on prototons, neutrons and lectrons and then on quarks and lepton but I aim to include more on Rutherfords experiment and Millikan.

I'll try to do a bit more but it takes time. Thanks for the feedback.

Roger at fizzicsorg

[andy123218]

helped alot!

[jess240991]

A excellent tutorial
