17+ Arrow Kinetic Energy Calculator. Learn how kinetic energy and momentum affect bowhunting performance and penetration. For example, my bow fires a 400 grain arrow.

By knowing the kinetic energy, one can predict how well an arrow can penetrate different materials and ensure their gear is suitable for their intended targets. Calculate arrow speed, kinetic energy, and momentum based on draw weight, draw length, and arrow weight. Measuring your arrow’s kinetic energy helps you determine whether your arrows have enough power to humanely and effectively take down your intended game.
