Objective:

To show conservation of angular momentum.

 
Apparatus:  
  • Rotating platform
  • Dumb-bell weights
  • Lab stool

Method:

The dumb-bell weights held in hands while rotating slowly on the platform can be used to show conservation of angular momentum. The arms are extended and withdrawn slowly.
