Links
Hi, this page is for any and all links to all useful resources online for studying physics, maths and science. If anyone reading this thinks I've ommitted a useful site, feel free to let me know and I'll try to include it. There's also a recommended reading list here.
PhysicsNet
A helpful revision site that contains an overview of each topic for GCSE and A level. Also contains a glossary of words, so can be helpful for learning definitions- I would suggest that the depth isn't too great, but it's a good place to start and to make sure you understand the basics.
HyperPhysics
Another helpful website, this time the detail is much more thorough. You will almost certainly not be able to read the entire thing, as it has sections on pretty much every physics topic imaginable, generally at A level or higher standard. I often find it as one of the top Google hits while researching a topic, and it's generally very helpful.
Institute of Physics
Great for everyone interested in physics- highlights for students include free access to their E-zine (you can also pay for a paper subscription, but the on-screen version I find more convenient) and the 'teaching advanced physics' section, which includes free lesson plans so that you can teach yourself, or go over stuff you did in class. I haven't gotten around to checking them, but there also some lectures on there.
Isaac Physics
The site (run by the BPhO, more on that later) has practice questions on physics and maths, across a range of difficulties. Definitely something to keep an eye on, although they don't have too much content up yet (e.g. Physics is pretty much just mechanics). Oh, and a word of warning: they are brutal when it comes to sig figs.
Found this site a while ago, it has worksheets with answers for all physics boards I think, along with notes to go with them. Definitely worth using, especially if you're not doing AQA as that's mainly what this site is geared towards. Additionally, it's pretty much the best site for obtaining maths past papers and Solomon papers.
If you take maths then you are probably aware of this site - it's got excellent videos explaining how to solve each type of problem that commonly occurs in maths exams. The link here is to the M1 Mechanics unit, which has a heavy overlap with As Mechanics. (If you don't do A level maths then I reccommend you try to learn all of M1, and most of M2. Then try to get up to at least C2 if you have the time, and C4 if possible.)
The homepage for the British Physics Olympiad- the place to go when you're confident with A level physics. Contains information about competitions, and past papers for you to try your luck on. There is also a particularly helpful resource called 'upgrade your physics', which attempts to bridge into first year undergraduate work, and covers a sightly broader curriculum than A level physics. Be wary ye who enter here.
The Student Room
If you haven't heard of TSR, it's pretty self explanatory- it's a student forum. The link above goes to the 'help about physics' section. Feel free to ask any questions you have there (or you can ask me of course...) and I'm sure the other students and some teachers will be happy to help you.
xkcd / What If?
Xkcd describes itself as "A webcomic of romance, sarcasm, math, and language." Read a few comics, bookmark it, then come back here. Some are unbelievably cute, some can only be described as the work of a 'classhole' and some are downright ridiculous. You'll love it.
What If? on the other hand generally tends to be downright ridiculous 100% of the time, and is a fantastic first course in what physicists call Fermi Estimation. If you like xkcd, you'll like What If? If you somehow don't like xkcd, then you might still like What If? because the universe must be exhibiting undefined behaviour.
There are quite a wide range of physics topics covered at some point or other on here. Of particular interest may be this textbook, designed for the OCR B specification and this highschool textbook which is designed for an American physics course. In addition to those two, this study guide also appears useful, although I can't really work out what level it is aimed at.
This website is geared towards people seriously trying to learn relativity, but without a strong physics background. It also includes a discussion of lagrangian mechanics (which is how I found it) and several brief essays on maths
This is a university textbook on Newtonian mechanics - whilst the first couple of chapters are approachable it fast becomes very difficult indeed. On the plus side, there are exercises at the end of each chapter, some of which are quite nice (e.g. the tautochrone problem is in there, albeit disguised).
