Gotthard Schettler,Hubert Mörl,Alfred WirthTo describe physical phenomena simply, one needs a suitable system of coordinates. For ballistic phenomena, we generally use the ., which is defined as follows: the x- and y-axes between them define a vertical plane, with the y-axis pointing in the opposite direction to the Earth’s gravitational pull.

L. S. Brandi,L. Santini,R. BertoliniThe two primary areas of ballistics – interior and exterior – had been seen as separate since the mid-18th Century. During the course of the 20th Century, a new subdiscipline emerged, covering the transition between the two.

Sympathetic nervous system and metabolismA ricochet always involves interaction between a projectile and a solid or liquid medium. The process therefore belongs to the field of terminal ballistics; it has already been mentioned in 6.1.5, in connection with the Backman-Goldsmith diagram. That diagram shows that ricochets can occur over a wide range of impact velocities and angles.
