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.
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.
This tool quickly calculates the kinetic energy of your archery arrow based on its mass and velocity. Arrow Mass (grains): Arrow Speed (fps): Calculate. Result (Kinetic Energy in ft-lbs): How to Use the Archery Kinetic Energy Calculator. To use this calculator, simply follow these steps:
To calculate the kinetic energy of an arrow, use this formula: \[ KE_a = 0.5 \times m \times AV^2 \] where: \(KE_a\) is the arrow kinetic energy (Joules), \(AV\) is the arrow speed (m/s), \(m\) is the arrow mass (kg). Example Calculation. If an arrow has a mass of 0.035 kg and is moving at a speed of 55 m/s, the kinetic energy is calculated as:
This calculator computes the kinetic energy of an arrow based on its mass and velocity. To use the calculator: Enter the mass of the arrow in grams into the “Arrow Mass” field. Enter the velocity of the arrow in meters per second (m/s) into the “Velocity” field. Click the “Calculate” button.
To use an Arrow Kinetic Energy Calculator: Measure the mass of the arrow, which includes the arrow shaft, tip (broadhead or field point), fletching, nock, and any additional components. Measure the velocity of the arrow as it leaves the bow, typically using a chronograph or other specialized equipment.
