  1. Ballistics practice quiz

  2. Which projectile has more energy, handgun or rifle? • Rifle

  3. How many moles of gas are produced when 1 Mole of gunpowder burns? • 6 moles of gas

  4. Name two ways to improve the accuracy of a projectile. • Barrel length & rifling the barrel

  5. What did the invention of gunpowder lead too? • Firearms

  6. Define ballistics • The science of a projectile in flight.

  7. What do they call the spiral groves cut into the barrel of a gun? • Rifling

  8. What factors influence the drag on a projectile? • Velocity & Spin

  9. What civilization invented gunpowder? • Chinese

  10. What is A • Casing

  11. What is B • Projectile/Bullet

  12. What is C • Powder

  13. What is D • Primer

  14. What type of casing is this? • Rimfire

  15. At what range was this projectile fired from? • Point blank

  16. At what range was this projectile fired from? • Close range

  17. At what range was this projectile fired from? • Distance

  18. What type of casing is this? • Centerfire

  19. Define Lands and grooves • Lands are the metal inside the barrel left after the spiral grooves are cut to produce the rifling.

  20. Define Ballistics • the science of the travel of a projectile in flight.

  21. Define silencer • A device that fits over the muzzle of the barrel to muffle the sound of a gunshot. Most work by baffling the escape of gases.

  22. Define caliber • The diameter of the bore measured from land to land, usually expressed in hundredths of an inch (.22 cal) or in millimeters (9mm).

  23. Define cartridge • called a "round". Made up of a case, primer, powder, and bullet.

  24. Define bullet • The projectile. They are shaped or composed differently for a variety of purposes.

  25. Define hammer • A metal rod or plate that typically drives a firing pin to strike the cartridge primer to detonate the powder.

  26. Name the four improvements made to guns by the military. • Reliability of firing Accuracy of projectile Force of projectile Speed / Rate of firing

  27. What are the two main ways the accuracy of a firearm was improved? • Barrel length Rifling
