To calculate your arrow’s kinetic energy you need to know two variables: 1) your total finished arrow weight in grains, and 2) the velocity of your arrow. Arrow weight is measured on a grain scale and arrow velocity is found by shooting through a chronograph.
Use the arrow kinetic energy calculator to estimate both K.E. and M. Using an Arrow Kinetic Energy Calculator for Bowhunting. Because both involve calculations of mass and weight, kinetic energy (K.E.) and momentum (M) are often interchanged, but that’s not right.
21 lut 2024 · Arrow Kinetic Energy Calculator. Kinetic energy (KE) is a measure of an arrow’s ability to transfer energy upon impact, and a higher KE can result in greater penetration and stopping power.
Arrow Ballistics Calculator. Divide by 32 for standard. Velocity estimate assumes equal kinetic energy for each arrow weight. KE will actually increase slightly as arrow weight increases as bows are more efficient as arrow weight increases.
Simply stated, kinetic energy is the result of an arrow’s weight and speed. Those elements are what is needed to calculate kinetic energy. For example, my bow fires a 400 grain arrow (broadhead included) at 305 feet per second. To find the kinetic energy, I multiply 305 by 305, then multiply by 400. I get 37,210,000.
The arrow ballistics calculator below will help you determine your arrow’s vertical drop, speed, kinetic energy and momentum, for up to 70 yards out in 10 yard increments. You will need to provide total arrow weight and initial speed for the calculation to be effective, as well as some other optional info (see below).
Kinetic Energy is the power potential of the arrow at the target, which is based on the arrow’s weight and speed. Optimal Bow Hunting Kinetic Energy Range: Small Game: 25 ft/lbs. Medium Game (Deer, Antelope): 25-41 ft/lbs. Large Game (Elk, Black Bear, Boar): 42-65 ft/lbs.
