A well planned site with lots of informations in Physics!

This is a great resource for IB Physics teachers. I have been using it and will continue using the same in future. The resources of IA are great. I can strongly recommend to any Physics teacher of the world for this site. Thank you for maintaining the...

I was new to teaching IB and moved to a brand new school with no other Physics teacher and no resources at all... With the huge help from the InThinking Physics site I was able to put in place a course with no problems at all. It has been like having...

    Try this Students are only expected to understand the basic rules

    I am confused about Feynmann diagrams. Id there a site which explains this ? For example scattering off a electron antineutrino off a muon. If it says just muon is it positive or negative ?

    HI Jaya, Thanks for reporting. It should be fixed now. Try reloading page and if still a problem clear the cache from your browser history.

    Hi, the equations in this entire section are not showing up

    It would do but there is no requirement for title, contents or appendix.

    Hi Chris, First of all thanks for the answer to all my other questions on this website, much appreciated. I have a question more to do with structure. Does the page count include the title page, the table of contents, the references list and...

    I think it is fine to use Algodoo in this way, wouldn't be easy to do it in real life.

    Ps. I am not teaching Imaging as an option so that is a new topic for him.

    Thanks, Chris :) Another question (sorry this is my first year with IAs and I have a lot of questions). A student of mine is proving the lens equation and he is using Algodoo to show the focal length changes with the refractive index (he is...

    I really like question 2, but the given angle is not possible if the ball has no vertical acceleration (weight does not equal vertical component of T). I was really proud of a student who recognized this method of solving using Pythagoras'...

    Yes they can but I think it is much better to compare the simulation to real life. I also think that it is much better for a student to build their own simulation in Geogebra or Algodoo than use a ready made one.
