Admit it or not, you use both velocity and mass an in your calculations - not velocity alone.
Which means you are using energy calculations.
He is applying the Newton 2nd law of motion Force calculation not an Energy calculation.
F= ma.......presence of velocity/acceleration means the mass has direction, which energy does not.
one only achieves an energy value by means of the directional mass F calculation.
Coroners go about formally describing tissue damage as result of blunt force trauma or sharp force trauma,
not blunt ft/lb trauma or sharp ft/lb trauma.
this page 1 comment is correct:
"Ft-Lbs energy" is not a wounding mechanism. .
and this comment is also true , even though nobody claimed energy was not required.
Work cannot be performed without energy....
*****
Bullets expend energy as they travel through tissue, quantity of energy lost is equal to the work done on tissue
– such work is determined by
forces acting over distance.
The directionless value of energy is only a measure of potential wounding, it is not in itself a mechanical action,
process, technique or instrument of wounding.
