tokamak physics thread 4

Thanks Eric, i did see them but wasnt too sure how to use them, got it sussed and working now, ta :-)

Ive got my Y gravity to -20 at the mo? havent played with that too much, my object is set to a mass of 300, but falls slooowwwwww, and if i set gravity any higher, my objects start squashing into each other and/or the floor.....
