Please note that this video relates specifically to the AQA specification for exams from 2014, though the concepts covered are relevant to other exam board course specifications too.
DISCLAIMER:
These videos are a revision guide designed to help students understand the requirements of the GCSE Science course, specifically the course specification(s) mentioned above. Although I say I can "help" students achieve a C grade, this should in no way be interpreted as a binding promise that this will definitely be a student's final grade. I offer expert guidance to try to improve a student's chances, but as there are so many factors beyond my control, I am unable to make any guarantee about the content of any exams or controlled assessments beyond any restatements of the relevant section or sections of the course specification(s). In my experience, a student's final grade is mainly dependent upon the quantity and quality of preparation he or she puts in. All I can do is try to optimise this preparation. In short, no-one can guarantee a grade; I'm just here to help.
Got my results a few days ago and I spent hours and hours watching your vids and it's helped a lot man - I got my c 👌🏿👌🏿👌🏿
ThePianoMan1999 Good work, well done!
Can you do GPE, please? I have a test tomorrow, and I know you won't be able to get it up in time, but for future revision, that would be great. Thanks for the amazing videos!
If you haven't already please could you do videos on electrolysis and lenses, I don't understand them but I find the way you explain things very easy to understand and its very helpful;, thank you!
I'll add lenses to my list, but I already have electrolysis videos here:

have my GCSEs soon and your videos have boosted my grades, thank you !
Thanks Sir, This has given me a much better understanding of this topic. I've got a high D in the mock GCSE's, hopefully I can "Get that C" in the upcoming practice papers I do. ^^
NRG Flash Good work! The grade boundaries are only usually six or seven marks apart, so you've got four months to pick up just four or five marks. That's totally do-able. Keep practising those past papers (and watching my videos ;) ) and you'll make it no problem.
Even better, ask your teacher if you could try a higher paper. Who knows, a B could be in reach. Show your teacher you can do it and they've still got time to enter you for the higher tier instead.
Hiya, your videos have been really useful. would you be able to go through velocity time graphs, meiosis and mitosis , aerobic and anaerobic respiration
revising for this years exam!!!!! good luck and thank for the vid sir
I am doing am applied Physics with technology Class through my high School and this video relay helped me thank you.
Great work, Mr. Would you be able to cover the topic on P2 Circuits? The 'standard' circuit, and the symbols etc. Thank's in advanced :)
George Harris Thanks! I'll add circuits to my list.
Could you please do a video on momentum :3
hello MR. Christopher Thornton, I had problems with transformers. It would be great if you help us on that.
Just did my mocks and got an A in Physics. Thanks a lot!
+Izmail .H I feel like your videos are heading me into the right direction for an A* at GCSE
What is the difference between how you work out a moment and how you work out work done?
The British Sabre Excellent question - you're absolutely right, the calculation (force x distance) is the same for both. The difference is in the situation:Work done is when you have to use energy to move an object in a straight line, e.g. pushing a box along the floor against friction, or lifting a heavy object working against its weight.
Moments occur when you've got a force turning some kind of lever around a pivot, e.g. a seesaw, or forcing the lid off a tin of paint with a screwdriver.
If you're doing the AQA course, work done is in P2 and moments are in P3 (i.e. you won't even use them unless you're doing triple). I hope that clears things up!
thank god I found your channel just coz of your videos
These videos are so helpful, I have not had a very good teacher for my physics GCSE and your videos help me a lot. I have 2 physics exams tomorrow because I do triple science. Hopefully I'll get a C after watching these videos :)
me too :/
I'll be crossing my fingers for everyone :)
what is the good example of work done by cosntt and variable F for matrix class student in daily life
Could you do a vacuum video of you haven't already :)
thanks! it helped a lot.
No problem :)
Hello your videos are really helpful, can you please do a few questions from past papers?
+Killer Cats Unfortunately exam papers are covered by copyright. It would be illegal for me to reproduce them here. I wish I could 😕
The force should be Balanced or unbalanced??
Great video, helped me a lot!
Great, glad to help!
:)
Can you make a video about electromagnetic radiation
ATplaza plaza Yes! I've added it to my list. Thanks for your comment.
oh and speciation if possible please!
A lecture on Electromagnetic Induction please
can u please cover physics electricity
Plz tell me something about centripetal force sir plz plz
could u pleze do elastic potetntial and gravitational potenitail as soon as because quick hav a test in 2 weeks please thank u
+Iftequar Hussain how was it
Is typing on a computer keyboard consider doing work in physics sense?
Hello
Oh, hello, I must've missed your comment before. Sorry about that. Typing on a keyboard will involve a small amount of work as you move your fingers, but not really very much.
hello again, does the object have to be heavy to be consider doing work on it?
The heavier it is, the more work you have to do to move it.
MR THORNTON CAN YOU DO gravitational potential energy for p2 aqa
I'll add it to my list.
Christopher Thornton thank you
cabn u please do could u pleze do elastic potetntial and gravitational potenitail as soon as because quick hav a test in 2 weeks please thank u and PLEASE CAN U GO OVER SOME PREVOIUS EXAMS PAPERS ON BILOGY PHYICS AND CHEMISTRY BRUUH YEH is that okay sir?
+Iftequar Hussain I'll add the potential energy topics to my list, but I don't think I'm going to be able to get them done before your test - it takes me quite a while to make videos. Also, because past exam papers are covered by copyright, I can't legally reproduce them here unfortunately. Wish I could.
+Christopher Thornton hw about if u did past papers for instance 2014and go over the questions which will really be helpful to the students as well as me if that's alright because im havin my gcses this year thank u
+Iftequar Hussain Copyright lasts for 70 years, so 2014's papers are still covered by it and I can't reproduce them. Sorry, but that's the law.
have you covered isotopes cuz i cant find it?
+hazza horan I filmed it a few days ago and it's partially edited so far. It'll be up over the holidays :)
+Christopher Thornton thank you
is this true??
jason statnam is a physics teacher
😂
circuit?
Reuben Demby I'm sorry, I'm not sure what you mean. Please could you clarify a bit?
could you do circuits like how they work? and more p3 stuff
Reuben Demby Thanks for the reply. Yes, I've already got circuits on my to-do list, and quite a few requested topics are P3 ones too.
okay thanks!;)
could you do b grade videos
+Bob Khan I explain in this video: ruclips.net/video/DNZ-JhwvxNg/видео.html
Atoms elements and compounds l
The videos on Electron Structure and Ionic, Covalent and Metallic Bonding from this playlist might help: ruclips.net/p/PLhzZT1_v76sDBcjfpC4cKLXCsFAepdGj7
Josh Jones sent me
+luca croft Welcome, and thanks Josh too :)
+Christopher Thornton my physics exam is this week so let's hope you get me that C ;)
