Speed

The speed is a parameter of external ballistics and describes the elongation of the trajectory of a ballistic projectile.

Speed ​​number: quotient of firing range s and peak h above the line of sight

With a horizontal shot, the dimensionless speed number indicates the ratio between the range of the shot and the distance between the top of the track and the line of sight: ${\displaystyle R}$ ${\displaystyle s}$ ${\displaystyle h}$
${\displaystyle R={\frac {s}{h}}}$

The speed number is always greater than zero and the higher the speed number, the longer the trajectory.

Speed ​​is an important parameter of firearms. The flatter the trajectory, the greater the area of direct fire in which the effort to aim a weapon at a target is least and external disturbances have the least effect.

The pace increases with increasing initial speed and cross-sectional load . Guns with high speed values ​​are summarized in the flat-fire guns category .
