   Format: MarkdownItexprompted by the discussion in [another thread](http://www.math.ntnu.no/~stacey/Mathforge/nForum/comments.php?DiscussionID=3068&page=1#Item_1) I have started creating stubs * [[rigid body dynamics]] * [[angular velocity]] * [[angular momentum]] * [[moment of inertia]] * [[Geometric Algebra]] But not much real content there so far.

   prompted by the discussion in another thread I have started creating stubs

   • rigid body dynamics

     • angular velocity

     • angular momentum

     • moment of inertia

   • Geometric Algebra

   But not much real content there so far.
