11. An important advance in the art of gun laying came with the introduction of the first recoil energy . 12. "' Free recoil "'is a vernacular term or jargon for recoil energy of a firearm not supported from behind. 13. In the firearms lexicon, the energy of a recoiling firearm is called felt recoil, free recoil, and recoil energy . 14. The recoil energy is generally absorbed by the mechanism which produces the counter-recoil force, and is dissipated as heat. 15. Therefore, free recoil stands as a scientific measurement of recoil energy , just as the room or outside temperature is measured. 16. In a rifle, this will develop well over of free recoil energy if an efficient muzzle brake is not used. 17. Trying to figure the net recoil energy of a firearm ( also known as felt recoil ) is a futile endeavor. 18. In these cases, since the recoil energy is negligible, the emitted gamma rays have the appropriate energy and resonance can occur. 19. Free recoil, sometimes called recoil energy , is a byproduct of the propulsive force from the powder charge held within a thermodynamic energy. 20. In a 110lb rifle, this will develop well over 200ft-lbs of free recoil energy if an efficient muzzle break is not used.
