Get Bow And Arrow Potential And Kinetic Energy Images. Learn how to calculate ke and how much you need for hunting. After measuring both the arrow speed and draw length, i can make a plot of kinetic energy vs.
In the case of a bow and arrow, the energy is converted from the potential energy in the archer's arm to the potential kinetic energy :
The energy should stay constant from the potential energy through to the kinetic energy. Kinetic energy of an arrow can be found by using the formula ke=(mv²)/450,240 where m = mass of the arrow in grains and v = velocity. Assuming there is no air resistance or loses due to friction with the bow, etc. If the arrow mentioned is released from the bow it then has kinetic energy.
