#1: Kinetic energy drops are fairly predictable. You can assume, roughly, that an arrowâs kinetic energy is reduced by around 3-4% for every 10 yards it travels. So if we have 100 ft-lb initial energy (at 0 yards), at 10 yards you can expect roughly 97-97 ft-lbs. of KE. This is a good rough rule to remember in case you need to do some quick on-the-spot kinetic energy calculations in the field.
