A = bow riser/grip, B = median plane of the bow, C = arrow aiming line and trajectory Arrow flexing both towards and away from the bow handle. The archer's paradox is the phenomenon of an arrow traveling in the direction it is pointed at full draw , when it seems that the arrow would have to pass through the starting position it was in before ...
A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight, with the trajectory subsequently governed by the laws of classical mechanics, in contrast to (for example) a cruise missile, which is aerodynamically guided in powered flight like a fixed-wing aircraft.
Shooting sports is a group of competitive and recreational sporting activities involving proficiency tests of accuracy, precision and speed in shooting — the art of using ranged weapons, mainly small arms (firearms and airguns, in forms such as handguns, [1] rifles [2] and shotguns [3]) and bows/crossbows.
The bow's primary purpose was to shoot birds, as conventional weapons lacked the ability to effectively hunt flying prey. [5] The lighter projectiles from a pellet bow flew faster, so the shooter had a better chance of hitting a moving target. One of the most important changes to the bullet-shooting crossbow was the strong, upwardly curved bow. [5]
Estimates for the draw of these bows varies considerably. Before the recovery of the Mary Rose, Count M. Mildmay Stayner, Recorder of the British Long Bow Society, estimated the bows of the Medieval period drew 90–110 pounds-force (400–490 newtons), maximum, and W. F. Paterson, Chairman of the Society of Archer-Antiquaries, believed the weapon had a supreme draw weight of only 80–90 lb f ...
Ballistics (gr. ba'llein, "throw") is the science that deals with the motion, behavior, and effects of projectiles, especially bullets, aerial bombs, rockets, or the ...
Transitional ballistics, also known as intermediate ballistics, [1] is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized, so it lies between internal ballistics and external ballistics.
The BoW representation of a text removes all word ordering. For example, the BoW representation of "man bites dog" and "dog bites man" are the same, so any algorithm that operates with a BoW representation of text must treat them in the same way. Despite this lack of syntax or grammar, BoW representation is fast and may be sufficient for simple ...
