Am I the only one that got so excited when I saw his calculator? I've never seen a pink colored one. Kinda weird for me but I want it. This video was useful to me, covered the chapter beautifully 💕
I am about to enter Year 12, a huge step between GCSE and A-Level and your videos are really helping me to get a head start into A-Level, keep up the good work Sir!
This video has A level physics content which wasn't much focused by our teacher in school so I used to stumble on these whenever they came in paper. But this video is a rich package and I direly needed it. Thnx:)
Thank you so much for the video and timestamps, it explained the content incredibly well so far and I'm only 10 minutes in! Starting A level Physics in September, it seem like these videos will prove to be very useful!
@@orwxh2154 yeah I guess. It’s also pretty handy to just read through your revision guide I think so you’ve got an idea of everything you do throughout the year
Hi there, I find your videos well explained and very informative. Is there a possibility that you could make it possible so that I may be able to download your mind maps for each of your videos? For example, when making a video, you would take a picture of the mind-map and put it on your website so that we can download it. That is if you have any time. Thank you, Sir!
Answer this question for me, please, is a head scratcher: 1.0 cubic centimetre (cm^3) of a solution contains 0.010g of salt. What is the mass of salt contained in 1 cubic decimetre (dm^3) of the same solution? Textbook says 10g but I disagree, my answer is 0.1g Which answer is correct and Why???
If I may be so bold, I think precision = the number of decimal places your data is measured in rather than the consistency across a data set. Consistency across a data set is called 'reliability' I think
@@PhysicsOnline Do you mind outlining the differences? Thanks regardless. I started using your videos, I think, around beginning of December to mid-December, and although it is AQA and our board is Edexcel, it still is really helpful. So thank you. 😁
At the end of the video can you have 10 seconds where your hands aren't on the mindmap so we can copy it down for revision without watching the entire 30 minute video.
hey man. can you use another pen please. the sound of the pen is very annoying for me and therefore it makes me not want to watch videos. other than that keep it up my g

Hah my maths teacher has that calculator

Hi, how are you finding year 12?
@@brendon5139 found it really hard to be honest with online lessons and lockdowns.
@@brendon5139 mate im watching these before my Y13 mocks and im learning stuff haha

Centi is 10 to the minus 2
Yeah
Wow
I've got a paid subscription to your website, it amazing for specific areas of specific topics! But these overall videos are such a lifesaver!!
I’ve spent the day planning the next videos like this for the year 13 topics!
@@PhysicsOnline I wanted to buy the subscription, are there year 13 topic recaps like the ones you did for year 12?
@@Litkeen Not yet, but there will be in time fore the 2024 exams
Thank you so much for the video and timestamps, it explained the content incredibly well so far and I'm only 10 minutes in! Starting A level Physics in September, it seem like these videos will prove to be very useful!
Are you going to cover all the topics in A Level Physics? If so, when will these be uploaded by?
ASAP
@@PhysicsOnline that was 9 months ago...
Yeah
@@DrTiger-qn5gv bit rude-
I'm an A level and equivalent physics tutor and this resource is incredibly useful, thank you.
Glad it was helpful!
This video is saving my life for my first Physics exam in class tomorrow thank you so so much!!
Wow I am new to this channel and I just have to say you have amazing content.
Glad you enjoy it!
@@PhysicsOnline about the premium plan on your website, does it follow the specification in order?
I'm looking for a video lesson for Year 12 physics during lock down, this'll do
I'm trying to do the same. Did watching these videos help you?
@@orwxh2154 yeah I guess. It’s also pretty handy to just read through your revision guide I think so you’ve got an idea of everything you do throughout the year
@@Sea-qv4sd Thanks :)
Hi please please please do the rest of the topics they’re amazing!!!!
@Physics Online please do all of particles, it would be so good Thank you

Thank you for explaining so clearly!
Nice video. The pen is mightier than the sword. I need to get a V5!
I am from south Africa and this is helping alot for my course in uni
Is this video useful for OCR too
It is useful, but I'm planning an OCR specific one too!
i’m starting physics right now😭 and this is so helpful
8:48 i thought my video lagged
lol
HOW COME I DON'T HAVE A PINK CALCULATOR?
Could you do a video covering the required practicals in this years advanced info and the possible types of questions you get asked on them.
Clear explanation
Sonisinghphys
You should make a video about particle physic too!!
Answer this question for me, please, is a head scratcher:
1.0 cubic centimetre (cm^3) of a solution contains 0.010g of salt. What is the mass of salt contained in 1 cubic decimetre (dm^3) of the same solution?
Textbook says 10g but I disagree, my answer is 0.1g
Which answer is correct and Why???
10g, there are 10cm in 1 dm, but 10^3 cm^3 in 1dm^3
Perfect lecture 🎉
If I may be so bold, I think precision = the number of decimal places your data is measured in rather than the consistency across a data set. Consistency across a data set is called 'reliability' I think
Aqallah says that precision is consistency across data unfortunately.
is this video useful for CIE AS levels students as well?
Im in my AS (no pun intended) and I found it quite useful
We're not in maths we're in the real world😭😭😭
An amazing video
Cheers 💯👔
Explained clearly sir
Is this the same for Edexcel?
Similar
@@PhysicsOnline Do you mind outlining the differences? Thanks regardless. I started using your videos, I think, around beginning of December to mid-December, and although it is AQA and our board is Edexcel, it still is really helpful. So thank you. 😁
an amazing video
how would you find the uncertainty from a multimeter measurement if you only took one reading for each measurement
do you have an aqa video on whole of particles and radiation topic?
At the end of the video can you have 10 seconds where your hands aren't on the mindmap so we can copy it down for revision without watching the entire 30 minute video.
Can you make a full recap for Particle Physics/Quantum? These videos are really good! Thanks Sir
26:05 why is it y plus z but the % is x = y/z ?
7:20 for uncertainty
Last minute revision
THANK YOU WTFFFF
7:30 - *shoots mathematicians*
I never remember prefixes all mentioned on the calculator
watching from spain

Anyone else watching before tomorrow?
