The acceleration is reduced by: How would it compare to the foregoing case of let us say "controlled expansion"? Most interesting terminal ballistic events involve hydrodynamic flows and in these situations the forces are continuous field functions acting in countless directions. I frequently encounter the attitude on cyber forums that physics and biology cannot really answer our questions about terminal performance, that it all comes down to some kind of personal thing, like faith, or that it is far too complex to ever understand or quantify. For a long time the Norman conquerors did not mix much with their Saxon subjects.
Cutting edge research
Several alternative methods have been promulgated. The bullet was completely stopped; it lay on the ground in front of the mesh screen. I've asked people who have been shot to describe their sensations of being shot, physical reactions, etc. If these are severed death can occur within minutes. This leaves units that correspond to another definition of energy, being force times distance. So, the hard fact is, that even on the most fundamental level the simplistic view of the conservation of momentum is not perfectly true. But how do you measure this or make any predictions about penetration from it?
Science does not merely belong to scientists nor only in the realm of the scientific journal. In the morning, your feet will be slightly moistened and soft. Within the West itself certain cultures rank time much lower in over-all importance than we do. Second in penetration among these bullets was the InterBond at After about an hour, you should start to taste and smell the garlic.
Lethality Index John Wooters is another old salt who ought to be listened to reverently. Fewer steps until it collapses? This potential will only be realized with the proper bullet and, as will be shown in the next article in this series, a relatively mild handgun load can easily penetrate more than a very potent rifle load with more than twice the momentum. Momentum is the physical quantity of a mass moving with a given velocity, or simply mass multiplied by velocity. A better understanding will follow. Again, the force of the blow is comparable to the recoil of the gun. It is velocity, not kinetic energy, which is the quantity of greatest interest in the terminal ballistics of small arms.
