Create a space environment with no gravity, Box2d or not?

Question

I want to create a cclayer with 4-5 flying objects, flying in random directions on screen. I also want those flying objects transparent to each other, which means they can fly through each other.

What I can think of Ways to do:

With Box2D

Create a box2d world with 0 gravity. and add Polygon static ground around the edges of the screen.
Give an initial force to each of the flying objects, let them flying around and reflect on the grounds.

Problems: Objects still rest down after sometime.. Don't know why. Objects collide with each other, don't know how to make them fly through each other.

Without Box2D

use CCMove for each objects, detect if they reach edge of the screen, calculate new path for their move..

Can someone point me a direction, which way is easier? Thanks a lot.

if you have to handle complex collisions - go with box2d. if they are simple - handle them yourself — Andrew, Mar 28 '12 at 17:30
You are right. Box2D is for collisions, gravity.. Thanks. If you provide an answer below, I will accept. Thanks a lot — Cullen SUN, Mar 29 '12 at 02:05
