Re: gravitational sensations--was Work/Energy theorem ?

["Richard W. Tarara" <rtarara@saintmarys.edu>]

We all experience the ground pushing up (or in my case the chair in front
of this computer pushing up).  But we _tend_ to interpret these upwards
forces as our 'weight'.  While in one sense these forces ARE our weight
since we really don't directly experience the gravitational force without
them, in most introductory sequences we define weight as the gravitational
attraction of a large body (like the earth) for smaller, nearby object,
such as ourselves.  Ultimately it is this confusion that leads us to call
the sensation in certain accelerating frames, 'artificial gravity'.
