   At the risk of sounding like Jim Bower, I would like to opint out that
   mechanical model was the original motivation for the momentum method.

   Geoff Hinton

The original motivation was fully discussed and acknowledged (by
citing Rumelhart, Hinton and Williams's chapter in the PDP book) in
the Introduction.  The paper went far beyond that by first showing
        m
p =  ------
     m + mu

(where p is the momentum parameter, m is the mass, mu is the friction
coefficient), and then providing a stability and convergence analysis
for both the continuous and discrete cases.
