The kinetic energy and momentum of an arrow are both important numbers and concepts to use when understanding the penetration potential of an arrow, which is especially important to bowhunters.

The most accurate numbers will be achieved when using the exact speed of the arrow, found by averaging multiple shots through a chronograph. If the exact speed is not available, use the Bow/Arrow Speed Calculator to estimate the arrow speed.
