Yes you should ignore the details of friction for the first few semesters.

  For how many semesters? All the way through to graduation?
  • rriepe 7y ago
    No. You wouldn't want people slipping on stage.

      > No. You wouldn't want people slipping on stage. Since all the students will merely be spheres of equal density, that shouldn’t matter much.

        I guess in that case you can also skip teaching them about angular momentum!

          They’d still have angular momentum; it just wouldn’t be immediately apparent.

    Funnily enough, you only solve problems with friction in your first semester (and maybe a little bit afterward when you study waves).
