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.

  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.
