  • Interesting fact: Ballistics is the science that deals with the motion of projectiles.
    • projectile Impelling, throwing, driving, or shooting forward: as, a projectile force.
    • projectile Caused by impulse; impelled or driven forward.
    • projectile In zoology, capable of being thrust forward or protruded, as the jaws of a fish; protrusile.
    • n projectile A body projected, or impelled forward by force, particularly through the air. Thus, a stone thrown from the hand or a sling, an arrow shot from a bow, and a ball discharged from a cannon are projectiles. The path of a projectile, or its trajectory (neglecting the effect of air-resistance), is a parabola.
    • n projectile Specifically, a missile intended to be projected from a cannon by the explosive force of gunpowder or some similar agent. Projectiles used in smooth-bore guns are usually spherical, though sometimes oblong, as is the case in the Manby, Parrott, and Lyle life-saving projectiles. Projectiles for rifled guns are oblong, the cylindroconoidal form being generally adopted. It is essential for the range and accuracy of such a projectile that it should pass through the air in the direction of its longer axis, and the only certain method of effecting this is to give it a rapid rotary motion about this axis. To this end the projectile must be so prepared that it will engage and follow grooves in the bore of the gun. This is done in several ways: By the flange system, in which the projectile is provided with flanges, studs, or buttons made of a soft metal, as copper, zinc, or brass, which fit into the grooves of the bore.

Between the crash of shell and shell
His laughter rings along the trench;
He seems immensely tickled by a
Projectile which he calls a "Black Maria."

In science:

Equation (4.1) is the specific form of the phase factor in the l ight cone gauge A− = 0 for a projectile moving in the negative z direction, so that the light cone coordinate x+ = (z + t)/√2 does not change during propagation through the target.

Jet Quenching in Heavy Ion Collisions
More generally, the eikonal for malism describes the interaction of any set of projectile partons with the target by a color rotation αi → βi of each projectile component i, resulting in an eikonal phase W (xi )αi βi .

Jet Quenching in Heavy Ion Collisions
Expression (4.14) illustrates that the gluon energy distribution (4.12) contains information about the off-shellness of the projectile parton, since it allows for gluon radiation without medium interaction.
