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. Hey! Thanks a lot for the notes! I just wanted to know where you took notes from, is it from the textbook Cambridge Tsokos?

    1. Hi, these are actually synthesized from quite a lot of sources, Tsoko included and other great resources such as physics.info.

      1. Hi David ! I’m taking IB physics this year and my teacher is not good at explaining anything. He is notorious in a couple of schools for his bad teaching. I was wondering if there was ever a time when you didn’t understand something in class and what you did when that happened ? Also I’m very grateful you made this site, I feel like I will be using it a lot! I want to study computer science 🙂 I’m also wondering if you got a tutor / extra physics class ever ? I’m just wondering in case I should do that. Thank you!

  2. Thank you so much! This website has been so helpful as me and my peers make our own study notes. just one suggestion though – there is a extremely helpful equation for closed pipes in unit 4.4. Rather than memorize 3 equations, you can use f=(nS)/(4l), where n = number of harmonic (1, 2 or 3, not 1,3,5), S= The speed of sound (330 m/s), and l=length of pipe. This was extremely helpful, and saved me a few marks on my in class final.

    Thanks for all the help!

    1. Hey, thanks for the suggestion! I believe your formula is a variation of the current one since v=fλ. Glad you found that this equation works best for you though. 🙂

  3. In Topic 3: Thermal Physics, in the FYI section for specific heat capacity, should thermal capacity not be given by Q = mc rather than Q=cθ?

    1. Hi! For clarification, c is the thermal capacity here. Therefore, thermal capacity = energy / temperature change.

  4. Hi David, firstly I wanted to thank you, this notes are really helping me, they are great!! I wanted to ask if you had for Math HL too, or where do you recommend us to get them from. Thank you!!!!

  5. i wasn’t that good in the 11th chapter, but your notes are really very good, that i am now able to answer any question! This is a very useful site! Thank you so much for providing such detailed and best notes!

  6. Thanks for the awesome website, my tutor gave me this website to revise and learn and for my IA, and its a go-to for me now!
