What would you recommend me to understand physics

[arkdemon]

Hello everyone .
I wanted to know what you would recommend me to read or to learn to understand how Newton or the world works. Currently, it is hard for me to use the library correctly, it's like I try functions and see what it does, and to debug errors too (it's not my primary language either - but I can understand in english, I'll just have to translate the terms ) or even to understand your answers (and then it makes you lose your time and then if I have anoter problem, I have to create another topic).
So what I am asking is: do you know some good links to learn physics?

Thank you very much!

Ps: I know I will only learn the basics (but it will help me a lot) and that I will need to work (I am willing to do that - I "learnt" C++ 3 years ago with a book of around 800 pages :3 )

Well, I can't really think of any specific site but GafferOnGames got some interesting articles describing some of the basics behind a physics engine and one article that has been really useful for me that explains why it's important to use fixed timesteps.

Other than that I suppose you could just google on different topics. That's how I learned how to use Newton. Googling and a lot of trial and error.

OK. I will look at that
Thank you!

Well I want to try to understand Newton better so that I only use the forum for 'non basic' questions :3 (I will learn physics later at school - from this year maybe to around 5 years - but it is hard to do what I want because I need some knowledge that I don't think I will learn this year and maybe next year and perhaps only in 4 years)

Something very easy an practical is this: http://www.gamasutra.com/resource_guide/20030121/jacobson_pfv.htm
Unfortunately the images are gone.
It's about moving particles in a very simple but physical way, also to model collisions and constraints.
You can make a small physics engine even without knowing what's acceleration or force.

GafferOnGames would be the next step.

And finally some more complex introduction to rigid body dynamics is here:

None of those handle the hard stuff like how to make a stable box stack, but as long as there are physics engines you don't need to know.

If you'r interest is about game physics, mechanics might be a better term to seek for a textbook.

Hello. Thank you for your answer
And sorry for the delay, I didn't have any internet access (the connection is still unstable :'( - the technician said we had to replace the 'box' but they haven't sent one after 4 days...)

I'll try to look at them whenever I can. It will be useful ^^
Thanks
