IB Physics

Hi, I’m David. This site hosts comprehensive IB physics revision notes I’ve made for the post-2016 examinations syllabus. I got a 7 and here’s how you can too!

Important note: Please take note that although succinct notes are essential towards your revision, they should not be the only materials you cover – working through practice problems from your textbook and past papers are just as important.

App: For revision on the go, download our Android app. If you like our app, don’t forget to give it 5 stars and send in a review!

Offline access: For offline access, download offline browser and type in ibphysics.org for the url.

Happy revising! 🧠

  1. You’re gonna have to get rid of the IB logo. They’ll probably be nice since you’re not making money on selling the app, but they have very strict rules on using their logo. Nice app though. I’ll recommend it to my students.

      1. Nice. Ya, I just know bc we are a full IB school from pre-k to grade 12, and already have PYP and DP authorizations but were just finishing the process for actual MYP Authorization. Even though we’re close, they told us to pull their logo from any exclusively MYP publications we make.

        Best wishes!

      2. Hey. I understand you achieved a 7 in physics HL. I have a question to ask. Did you work ahead for physics. If so, how ahead were you of the class when it came to content (e.g were you 4 chapters ahead of the class, 2 chapters, 0 chapters etc.) Thanks

      3. I actually worked alongside my class haha. But I do these notes to help my revision too (hint hint).

  2. Hello. I was wondering if you are going to include the other options for the course? We are doing imaging at our school and the notes you have are really helpful for the other topics. Thank you so much for the app, it is a lifesaver, even if you cannot do the other options I am happy with the extra help for all the other topics.

    Thank you so much!

    1. I most likely won’t do notes for Imaging (more likely doing one for Engineering Physics) though I will try to if I have time. Happy revising!

      1. Many of us would appreciate it so much if you do one of Engineering Physics before november exams. Thank you for the extra help for the other topics as well!

      2. I’d be really happy if you made notes for Option A, Relativity. Would be a life saver. Love this though, thanks a lot!

      1. I studied from the toskos 6th edition but I have bad recollection so will doing these revisions be enough? Ps I’m also doing past paper problems (I have my exams in may)

  3. ahhh! thank you so much for these, such a lifesaver :’) wish i’d found these before my paper 1 and 2 though 🙁

  4. Hi. This is really helpfull. Its a good tool for revising. Will it be possible to create them for other subjects like chem?

    1. I most likely won’t do notes for Relativity (more likely doing one for Engineering Physics) though I will try to if I have time. Happy revising!

  5. Hey david. I’d be appearing for my exams in 2017 and I had a question for TOPIC 1 whether we have to know all the orders of magnitude or just some of them? Thanks your notes are amazing and life-saving

    1. Hey Jason, pertaining to the orders of magnitude in Topic 1, you are not required to remember any of them although having a basic grasp of their relative ratios may be largely beneficial when checking your answers. Glad you find my notes helpful and happy revising!

  6. I downloaded the offline browser but when I typed in ibphysicsnotes.wordpress.com for the url but it says its invalid. Please help

    And thank you for the app, it’s really good

    1. I just tried it out and it seems to be working fine. If you’re still stuck, can you post a screenshot of your situation so I can have a clearer look? I’m glad that you have found my app helpful!

    1. Glad you enjoyed my app! IB Physics does not have a partner IB Math HL site for the time being. For revision, I personally recommend you going through past papers and working out your strengths and areas for improvement.

  7. Dear David,
    I stumbled on your good notes. Thanks a lot. I badly need Option C notes. Will you help please. Thanks.

  8. Dear David,
    Thank you so much. Its not possible to view your good notes without internet connection. Can you change this so I can have access without internet?

  9. In the solid friction part I think you made a mistake, it says “Friction force=µs *Normal force for objects that are moving.” I think you meant µk instead of µs. Besides that, really helpful.

  10. Hi

    May you please upload the notes for option d.8 and d.9 for medicinal chemistry…

    Trials are about to start and i don’t understand them yet and your notes are really helpful…

    Thank you.

  11. In chapter 7 i think there is a mistake in the baryons & hadrons section, u you have written that leptons have a charge of +1 and anti leptons have a charge of -1 whereas leptons contain electrons so charge is -1 for leptons and +1 for positrons/anti leptons

  12. Hey!
    Your website is insanely helpful! Do you know or have any links/pfds with practice papers! Hope you can help 🙂

    1. Glad you found my notes helpful! I don’t think it will be legal if I do that haha – check reddit though. 😉

  13. I really wish there was one for Computer Science. But still thank you very much for this it is very helpful.
    Thank you.

  14. Hi,

    Your notes are very helpful. Is there any way I can print them so I can highlight, annotate, etc.


  15. Thank you very much, it helped me a lot. But I really wish there was one for Computer Science. Overall thank you for your help.

    1. Glad you found my notes helpful! Ah, I wish I made them too – unfortunately, CS wasn’t offered in my highschool.

  16. Dear David… It is a very good app….Can you please give me your email address.. I need a small help from you…

    1. Glad you found my notes helpful. 🙂 For solved examples, try working through textbook problems and past papers!

  17. Hi,
    Great site for revision covering all the necisities within the topic. However, it would’ve been better with more examples and exam questions.

    1. Glad you found my notes helpful. 🙂 For exam questions, I suggest you work through past papers as they most accurately reflect what will be tested. (They also own the copyright to the questions.)

  18. Thank you so much for making this, and making it free. I would just like to enquire on the name of the app mentioned where offline access is available, as the link is not functioning, it says page not found. Thank you once again.
