  3. Ballistics (gr. βάλλειν ('ba'llein'), "throw") is the science of mechanics that deals with the flight, behavior, and effects of projectiles, especially bullets, gravity bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
  4. Ballistics is a futuristic racing computer game developed by GRIN and published by Xicat Interactive in 2001. GRIN developed an arcade version of the game, released in 2002 featuring a unique reclined seating position cabinet by Triotech Amusement. ...
  5. The Ballistics were a ska band from Ipswich, UK. Formed in 2002, they have built up a healthy following across the UK and have garnered airplay in the U.S., Germany, Argentina and Brazil. The band's first cd, Go Ballistic, was released in 2003 in an extremely limited run and sold out quickly. ...
  6. By definition, limited to the study of projectile dynamics. In practice, extended to the study of bullets, and the functioning of firearms.
