title:    Hooke's Law
aka:  Stretch a spring

A spring can be hung from the lecture room "sky hook" or a ring stand.  Weights are applied and the extension noted.
  An alternative way to do this is to anchor one end of the spring and pull it horizontally with a newton scale.

   Would the weight method work on the moon?  What would be different?
