The child as a projectile [PDF]
The Anatomical Record, 1998 Unintentional injury is the leading cause of death in children under the age of fourteen. The majority of these injuries/deaths occur when the child becomes airborne during an accident. The most common mechanisms by which children become airborne are motor vehicle collisions, bicycling accidents, and falls. A head injury is seen in a significant number

Implementation of a Realistic Damage Model in a Simulated Environment [PDF]
Problemy Mechatroniki, 2019 Realism is an important aspect of the virtual shooting range, which increases the quality of the shooting training conducted there. An important element of realism is the modeling of damage arising during the impact of the projectile on the target.

On the Air Resistance of Projectiles [PDF]
Proceedings of the National Academy of Sciences, 1931 In making this study, the author had in mind its applications to the problem of meteoric impact. The different laws of resistance, heretofore proposed, contain too many empirical or hypothetical elements to permit a safe extrapolation to cosmic velocities.
