How is kinetic energy calculated? Also, how should KE affect choice of broadhead? Thanks.

got to www.bowjackson.com and click on KE calculators,

the heavier the arrow the more KE produced out of any one bow.

(velocity * velocity)(arrow weight)
---------------------------------
450,240

For example, a 400 grain arrow traveling at 260 fps would produce 60 ft./lbs. of KE.

260 x 260 x 400
--------------- = 60.06 ft./lbs.
