Re: [Phys-l] momentum and energy

[Bernard Cleyet <bernardcleyet@redshift.com>]

Conserved by the collision may fix that?

Except as a project measuring the deformation / PE is beyond HS,  and 
I've not seen it done at the further ed. institutions with which I've 
been associated.  

bc,  a project for Mumford Micro?
