Kenitic Energy ?

[Holehog]

For the sake of discussion, lets say:

Case #1) A bow is set up to shoot arrows weighing 380g and delivers that arrow with 65 ftlbs. of impact energy.

Case #2) A bow is set up to shoot arrows weighing 480g and also delivers an arrow with 65 ftlbs. of impact energy.

Will the lighter arrows kenitic energy disapate faster?

How important is momemtum when considering arrow selection?

[Dr Strangelove]

IMHO, and it may be wrong, the lighter arrow's potential energy turns into kinetic energy at a faster rate on impact than the heavier arrow, because for "exact same impact force of 65#" then the lighter arrow must go faster
(E=MC2). Albert Einstein.

The rate of which potential energy is converted into kenetic energy, is that important?

My interest is to determine which arrow will maintain the highest energy upon impact at target distances. "not two feet in front of the bow"

Found the answers to my questions at WWW.bowjackson.com utilizing the interactive arrow balistics chart.

Thanks

the heavier arrow will and does carry more energy behind it,,,,,,,,,,,,,,
