### Ballistics

1. 1. Terminal Ballistics Anatomy and the Kinetic Energy Theory Explained<br />
2. 2. Terminal Learning Objectives<br /> Given a scenario indentify the terminal ballistics anatomy and the kinetic energy theory of medium to high velocity ammunition<br /> IAW Terminal Ballistics: A Text and Atlas of Gunshot Wounds and Gottfried Leibniz and Johann Bernoulli kinetic theory<br />
3. 3. Enabling Learning Objections<br />Describe the ballistic make up of medium to high velocity ammunition<br />State the theory of Kinetic Energy and Formula<br />Describe distribution of Kinetic Energy<br />Describe future innovations of disruption of Kinetic energy.<br />
4. 4. Definitions<br />Ballistics is to analyze the projectile trajectory, the forces acting upon the projectile, and the impact that a projectile has on a target<br />Kinetic Energy-is when something is in motion it is said to have kinetic energy <br />
5. 5. Types of Rounds<br />
6. 6. Bullet Anatomy<br />
7. 7. Kinetic Energy<br />When something is in motion it is said to have kinetic energy<br />Is the energy of motion which is moving. An object that has motion - whether it is vertical or horizontal, still has kinetic energy. <br />There are many forms of kinetic energy <br />Vibration ( shaking very fast)<br />Rotational (means moving in circles)<br />Translational (the energy due to motion from one location to another means moving)<br />
8. 8. Kinetic Energy Formula<br />KE= ½ M(V1-V2)2<br />M-is mass of the object<br />V- is speed (velocity) of the center of mass of the object<br />

13. 13. Bullets produce tissue damage in three ways<br />“Laceration”<br />“Cavitations”<br />“Shock Waves”<br />
14. 14. Bullets produce tissue damage in three ways “Laceration”<br />Laceration and crushing -A bullet can shred (lacerate) or crush tissue or bone<br /> Bullets moving at relatively low velocity do most of their damage this way <br />Fragmentation of bone can cause further damage, as the bone shards themselves become missiles<br /> Low velocity bullets, as in handguns virtually all their damage via crushing<br />
15. 15. Bullets produce tissue damage in three ways “Cavitations”<br /> A &quot;permanent&quot; cavity is caused by the path of the bullet itself<br />A &quot;temporary&quot; cavity is formed by continued forward acceleration of the medium (air or tissue) in the wake of the bullet, causing the wound cavity to be stretched outward<br />
16. 16. Bullets produce tissue damage in three ways “Shock Waves”<br /> Air at the front and sides of a very fast moving bullet can become compressed<br /> The explosive relaxation of the compression generates a damaging shock wave that can be several hundred atmospheres in pressure<br /> Fluid-filled organs such as the bladder, heart, and bowel can be burst by the pressure.<br />
17. 17. Bullets produce tissue damage YAW<br /> Definition of YAW<br />Is the term that is used for the tumble of s a bullet to turn sideways or tumble in flight. <br />This behavior tumble is the object spins as it moves forward <br />More damage results from a bullet that is tumbling rather than moving in a tight spiral<br />
18. 18. Bullet Tumble or YAW<br /><ul><li>Any elongated</li></ul> bullet when fired from a barrel with<br /> a smooth bore,<br /> it would tumble<br /> end over end.<br />

20. 20. Military Grade Ballistics <br />
21. 21. Military Grade BallisticsFragmented Round <br />
22. 22. Military Grade Ballistics <br />The round fragments upon impact at this high yaw angle (essentially travelling sideways), these bullets break on contact and the marked fragmentation, acting in synergy with the temporary cavity stretch, causes a large stellate wound with the loss of considerable tissue .<br />
23. 23. Future InnovationsDisruption of Kinetic Energy<br />
24. 24. Is This Possible?IBM files Matrix style bullet dodging patent<br />
25. 25. Is This Possible?<br />3 February 2009 IBM was issued a patent that in theory would give us mortals that ability.<br />The patent proposes a system where an external device monitors the area for incoming projectiles. <br />If it detects a projectile headed near a person hooked into the system it can either shock their muscles in order to move their body a particular way to dodge the bullet<br />Matrix style or it could simply make the intended target collapse.<br />
