The British engineer Benjamin Robins conducted many experiments in interior ballistics. His findings justly entitle him to be called the A. father of modern gunnery B. father of modern ballistics C. father of interior ballistics D. father of forensic ballistics 5. Late in the 18th century the Anglo-American physicist Benjamin Thompson made the first attempt to measure the pressure generated by gunpowder. The account of his experiments was the most important contribution to A. Exterior ballistics B. Forensic Ballistics C. Interior ballistics D. None of these 6. An arbitrary index of the quickness that burning propellant changes into gas. It is the rate controlled by the chemical composition, the size and shape of the propellant grains, and the pressure at which the burning takes place. A. Gas Power B. Burning Rate C. Propulsion Rate D. Bulk Density 7. It is the equal and opposite reaction of the gun against the forward movement of the bullet during the explosions. A. Residual Pressure B. Recoil C. Backfire D. Misfire 8. The speed per unit of time of the M16 is 3,300 ft/sec. This refers to: A. Fire power B. Velocity C. Energy D. All of these 9. It is the soft guiding metal which serves as the container of priming mixture, paper disc and anvil. A. Primer cup B. Primer mixture C. Paper disc D. Battery cup 10. The noise created at the muzzle point of the gun due to the sudden escape of the expanding gas coming in contact with the air in the surrounding atmosphere at the muzzle point. A. Muzzle Blast B. Muzzle Energy C. Range noise D. Fire power 11. What is the actual curved path of the bullet during its flight from the gun muzzle to the target? A. Yaw B. Accuracy C. Trajectory D. Velocity 12. The means that the bullet may lose its speed very rapidly during its flight the air. This is a number that relates to the effect of air drag on the bullet's flight and which can be used to later predict a bullet's trajectory under different circumstances through what are called "drag tables." A. Bullet trajectory B. Critical zone C. Ballistics Coefficient D. Down Range 13. The curve taken by the bullet while in flight is called A. rifling curves B. effective range C. drift D. maximum distance 14. The tumbling of the bullet in its flight and hitting the target sideways as a result of not spinning on its axis. A. Key-hole shot B. Back shot C. Mid range trajectory D. Point Blank 15. The power of the bullet that results in the instantaneous death of the victim is called A. Zero power B. Power ranger C. Shocking power D. Power range 16. What do you call the depth of entry of the bullet in the target? A. Terminal Velocity B. Terminal Penetration C. Terminal Ballistics D. Terminal Power 17.
