Re: ENERGY WITH Q

[Robert Cohen <Robert.Cohen@PO-BOX.ESU.EDU>]

I ask these questions because I want to know the proper vocabulary to use.
A couple more annoying questions...

Is kinetic energy the only "non-pretend" energy (i.e., energy that does not
include the likes of PE)?

If not, what are some other "non-pretend" energies?

Is energy conserved (i.e., energy that does not include "pretend" energies
like PE)?
