Questions and Answers

What are the two types of cavity caused by a projectile?

  • Superficial and deep
  • Internal and external
  • Circular and oblong
  • Permanent and temporary (correct)

    • What are the two destructive mechanisms of GSW?

  • Laceration and crushing, shock waves (correct)
  • Cavitation and bullet size
  • Bullet deformity and shock waves
  • Bullet size and laceration

    • At what velocity can generated shock waves reach up to 200 atmospheres of pressure?

  • High velocity (correct)
  • Velocity does not affect shock waves
  • Medium velocity
