Phy p3 2024 mon GL all. Hopefully its nothing like last years and our p2 ! Relativity in turning points is gonna be the end of me.

[@leoyakafudy]

at least relativity is pretty much just equations, but thinking which one is l0 or t0 or whatever is the bad bit

[@TomtheMagician21]

It's also helpful to know for the log graphs, if you go half way up, like you said it being roughly 3 (it's 10^½) and if you go 3/4 of the way up, it's roughly 5.6 (10^¾) Our teacher didn't teach us this at all so for the mocks I just had to use intuition

Single handedly saving our exams thank you

[@Arcadendo]

I love you Mr Shorts. Thanks for 2 years of great videos!

[@yoohoo1392]

Thank you for your services. It was highly appreciated❤

[@noorshah2038]

Thank you for your videos, they've been the best revision source these past two years :)

[@flynn5246]

This video is saving my paper 3 thank you

[@abidmo7168]

Can you please make compilation videos from the paper walkthroughs for specific topics, e.g All electricity questions from AQA papers 2016-2022 love your work

[@khaq446]

Thanks for all the help sir. Loved the reactions to the stupid aqa a level physics past paper questions really resonated with me.

[@subhan8325]

Hi sir, firstly ur a legend I love ur teaching style, secondly do you have a playlist covering year 2 of a level physics for aqa please ?

[@AmeyTripathi-dw6cs]

So grateful for your videos - you saved me in paper 3 today

[@shoyo7056]

is it reflected in mark schemes where giving uncertainty to the same value as resolution is the better option than 1/2 resolution?

[@ScienceShorts]

Yes.

[@edwardspencer-EDS]

I am not arguing but in the aqa 2023 paper 1 for the protractor you had to half to get the full 3 marks , I think it’s depends on the situation 🤷‍♂️

[@ScienceShorts]

They do seem to change their mind a lot, but more often than not, it's a whole. Even if the mark scheme says only one thing, you will get the mark either way. Trust me, I've had several conversations with AQA over the years about this.

[@bobvance8017]

@@ScienceShorts So is either one safe to use?

[@edwardspencer-EDS]

Okay 👍

[@user-yi8rb1rg8t]

You're a real hero among men

[@freshh32]

Just asking, but I heard that aqa do topics in a 3 year cycle, so I've gathered all the topics that come up for 3a, should I mainly focus on the ones that could come up(drill these topics & be confident) or focus on everything but be weaker at everything

[@S1mple-_-]

What topics do you reckon are coming up?

[@freshh32]

@@S1mple-_- g from freefall, emf, and motor effect came up last year, so the other 9 practicals are more likely to come up

[@bossgamer9411]

@@freshh32 it wasn't motor effect it was EM induction last year F=BIL wasn't 2023

[@AR2K77]

Required Practicals 2, 5, 7 and 10 came up the least out of all the papers so they're perhaps the most likely to come up

[@griefwnl7641]

When we use a ruler, even if we line it up and it can’t move , surely there’s still uncertainty in that at both ends?

[@ScienceShorts]

If lining something up with the 0 line, that's not the same thing as judging which line a measurement is closest to.

[@sanidufonsekaSL]

can u pls make videos for edexcel a level bio

[@griefwnl7641]

Is the uncertainty half the res for an analogue and just the res for a digital?

[@smokey2264]

res for digi and you can use either res or res/2 for analouge both widely accepted

[@abida7675]

Why is the uncertainty for a digital equipment equal to its resolution rather than half? I know you said halving it is more justifiable but I want to know how AQA do explain it?

[@ScienceShorts]

Because there is no judgement on your part

[@anvion1161]

Because it’s a reading not a measurement

[@jedwards4465]

shouldn't the percentage uncertainty at 5:56 for d be 0.5% not 5%?

[@ScienceShorts]

1 is 5% of 20

[@MiskoThief]

i was told by my physics teacher that in physics when coverting into y=mx+c form using logs, you should use the natural log in physics over log base 10, as apparently its what is usually in the mark scheme if they havent told you to do it in log base 10 instead of natural logs, is this true ?

[@tectR]

depends on whether the question (or the graph) is using ln() or log10()

[@harrisroberts5938]

Hey is it possible if you can post a video about aqa biology paper 1 that would be great

[@marcosseris]

Why would using analogue equipment ever be better?

[@szymlucky]

I saw this too and i was confused, however, if a digital ammeter only reads values up to 1 decimal place that second decimal place is rounded up or down to fit the 1dp accuracy. This causes inaccuracy. So in an analogue ammeter it wouldnt round any values as your the one reading the value off the ammeter so you can clearly see if the pointer is inbetween any 2 values. Also, i remeber someone mentioning how you can mark with a peice of paper certain reading on the analogue so that u can go back to them and write them down, however with a digital ammeter you cant store values so you might miss and be inaccurate with ur values if ur time interval is small. Hope that kinda made sense, PERSONALLY i would still pick a digital ammeter.

[@ScienceShorts]

For example, when you need to record the time when a measurement reaches a certain value, like when doing capacitor decay. As the needle is constantly moving, you don't have to wait for a number on a screen to change to know you've reached a value.

[@marcosseris]

@@ScienceShorts thank you 👍👍

[@mieispeeking]

I thought parallax error is a systematic error? Why is this case it's a random error???

[@ScienceShorts]

How can you get the same parallax error every time?!
