Forensic Ballistics Reviewer
1. A gigantic bow or catapult which was used to hurl large objects
such as stones at a particular distance to deter animals or enemy forces. A. Catapult B. Balle C. Ballein D. Ballista 2. The scientific study of the propulsion and motion of projectiles such as bullets, artillery shells, rockets and guided missiles. A. Propulsion B. Expulsion C. Repulsion D. Extraction 3. 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 4. 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 5. 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 6. 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 7. 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 8. 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 9. 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 10. 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 Answers: Forensic Ballistics
