Ball Bounces and Then Becomes Inert

I have a ball which bounces on a mesh object and comes to rest.

If I incline the mesh object programatically the ball remains in the same location, and the surface of the ball passes though the inclined mesh, instead of starting to roll in the direction of the incline.

Can someone please point me to a resounce to help me learn to achieve the physics behviour I require?

[SOLVED] I found that switching from ‘discreet’ to ‘continuous’ for collision detection solved it.

Sorry guys. Noobs eh?
