Historical Examples This cannon is a duplicate of the one used for […]
- Ballistic trajectory
the path of an unpowered object, as a missile, moving only under the influence of gravity and possibly atmospheric friction and with its surface providing no significant lift to alter the course of flight.
- Ballistic wind
a single wind vector that would have the same net effect on the trajectory of a projectile as the varying winds encountered in flight.
