Richard,
Collision detection is the easier part. Just calculate the distance between
centers and, if it is greater than the sum of the radii (assuming they are
circular) you have a collision.
The more difficult part is the physics, what happens after the collission. Are
they of equal mass and size? You need to conserve momentum and energy.
To get started you may look at a pool game. See:
http://jamesphurley.com/runrev.html
and look for "Nine ball pool."
You may want to also checkout "Bouncing ball tools" at the same site to see
how to work with collision with different shapes, and how to deal with
enclosures that are may be convex.
