Ballistics

Ballistics (from Greek βάλλειν ballein, "to throw") is the science of mechanics that deals with the launching, 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.

A ballistic body is a body with momentum which is free to move, subject to forces, such as the pressure of gases in a gun or a propulsive nozzle, by rifling in a barrel, by gravity, or by air drag.

A ballistic missile is a missile only guided during the relatively brief initial powered phase of flight, whose trajectory is subsequently governed by the laws of classical mechanics, in contrast (for example) to a cruise missile which is aerodynamically guided in powered flight.

History and prehistory

The earliest known ballistic projectiles were stones and spears, and the throwing stick.

The oldest evidence of stone-tipped projectiles, which may or may not have been propelled by a bow (c.f. atlatl), dating to c. 64,000 years ago, were found in Sibudu Cave, South Africa. The oldest evidence of the use of bows to shoot arrows dates to about 10,000 years ago; it is based on pinewood arrows found in the Ahrensburg valley north of Hamburg. They had shallow grooves on the base, indicating that they were shot from a bow. The oldest bow so far recovered is about 8,000 years old, found in the Holmegård swamp in Denmark.

Ballistics (video game)

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. Players race across seven different tracks in various leagues against other competitors on high-speed hoverbikes.

The game was Grin's first to be released, and featured the first version of their Diesel game engine. Grin worked closely with NVIDIA to incorporate then new technologies into the game, and was marketed as one of the flagship titles for the GeForce 3 Series of graphics cards.

Critical reaction was generally favourable, with reviewers being impressed by the beauty of the graphics and the thrilling depiction of speed. They were however, slightly disappointed with the shallow nature of the gameplay. A newer version of the arcade game was released in 2003, incorporating motion simulator technology into the arcade cabinet.
