Enter the arrow speed and the arrow mass into the calculator to determine the Arrow Kinetic Energy. 

Arrow Kinetic Energy Formula

The following equation is used to calculate the Arrow Kinetic Energy.

KEa = .5*m*AV^2
  • Where KEa is the Arrow Kinetic Energy (Joules)
  • AV is the arrow speed (m/s)
  • m is the arrow mass (kg)

To calculate the arrow kinetic energy, multiply the arrow mass by the arrow speed squared, then divide by 2.

What are the units for Arrow Kinetic Energy?

The most common units for Arrow Kinetic Energy are Joules.

How to Calculate Arrow Kinetic Energy?

Example Problem:

The following example problem outlines the steps and information needed to calculate the Arrow Kinetic Energy.

First, determine the arrow speed. In this example, the arrow speed is determined to be 45 (m/s).

Next, determine the arrow mass. For this problem, the arrow mass is measured to be 8 (kg).

Finally, calculate the Arrow Kinetic Energy using the formula above: 

KEa = .5*m*AV^2

Inserting the values from above and solving the equation with the imputed values gives: 

KEa = .5*8*45^2 = 8100 (Joules)
