Books or sites on simple physics

I'm hoping to improve my skill a little at maths and basic physics for games (mainly 2D) and would love some suggestions on books or sites that can help me learn this stuff.

I would like to re-fresh some math like trigometry, vectors, splines etc. I feel I need a better base to stand when it comes to doing more complex stuff. And then go on to learn more about physics for 2D games.

Any suggestions welcome.

www.wikipedia.org might have some stuff on that, or it may have a few websites or books at the resources of an article that describes those a bit

www.mathworld.com is great, if you can speak maths :)
and Hugo Elias http://freespace.virgin.net/hugo.elias/ should be in everyone's bookmarks.
