Re: [Phys-l] momentum and energy

[Bernard Cleyet <bernardcleyet@redshift.com>]

Classically (N)  p^2/2m = (identically)  m^2* V^2 / 2 m    Am I crazy?


If not, then,  lim:  m => inf.      (with v non zero*)   E => .    not zero

* Which I think agrees w/ jsd ==  i.e.  "you will find that V makes a 
negligible contribution to the golf ball velocity, but a nontrivial 
contribution to the conservation law."

Negligible is not zero?

bc, missing something?
