Lecturer Procedure

Steps to Follow

  1. Make sure that the masses are at the edge of the rod.
  2. Set in motion by giving it a push.
  3. Pull down on the cord, which will bring the masses toward the center immediately.

Expected Result

The speed of rotation increases immediately and angular momentum is conserved.
