Calculating Kinetic Energy Formatting Updated 2 December 2011 |
KE = 0.5 * Mass * Velocity^{2}
Where:
KE: Kinetic Energy in Joules (or foot-pounds)
Mass : Mass of the object in kilograms (or slugs)
Velocity: Velocity of the object in m/sec (or ft/sec)
Mass = KE / (0.5 * Velocity^{2})
Velocity = SQRT (2 * KE / Mass)
KE = 0.5 * Mass (V_{Muzzle} + V_{Target})^{2}
Where:
KE: Kinetic Energy in Joules.
Mass : Mass of the object in kilograms.
V_{Muzzle}: Velocity of the projectile in m/sec
V_{Target}: Velocity of the target in m/sec
