Select to solve for a different unknown. While most bowhunters pay an awful lot of attention to arrow speed its only one part of the KE equation. E k ½ mv 2 ½ x 500 x 20 2 05 x 500 x 400 Kinetic Energy.
KE 05 x m x v² M Mass V Velocity What this formula doesnt consider at higher speeds though is the relativistic effects.
Ie K ½mv² Power - Work done per unit time. Kinetic Energy is the energy an object has owing to its motion. Calculating kinetic energy The amount of kinetic energy in a moving object can be calculated using the equation. To compute for the kinetic energy two essential parameters are needed and these parameters are mass m and velocity v.
