Re: [Phys-l] momentum and energy

I am surprised and pleased to find myself on the side of law and order
 on this one.

An undefined physics symbol is just one step away from a symbol
used for various different  variables in subsequent paragraphs;
 both  features  often found in physics texts, and just one more way
to lose a student's grasp.

   When queried, the author ALWAYS says:   "But it's obvious".
Obvious to him no doubt.
