Bow (archery)
The bow and arrow is a ranged weapon system consisting of an elastic launching device (bow) and long-shafted projectiles (arrows). Humans used bows and arrows for hunting and aggression long before recorded history, and the practice was common to many prehistoric cultures. They were important weapons of war from ancient history until the early modern period, where they were rendered increasingly obsolete by the development of the more powerful and accurate firearms. Today, bows and arrows are mostly used for hunting and sports. Archery is the art, practice, or skill of using bows to shoot arrows.Paterson ''Encyclopaedia of Archery'' p. 17 A person who shoots arrows with a bow is called a bowman or an archer. Someone who makes bows is known as a bowyer,Paterson ''Encyclopaedia of Archery'' p. 31 someone who makes arrows is a fletcher,Paterson ''Encyclopaedia of Archery'' p. 56 and someone who manufactures metal arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Archery'' p. ...

Bowyer
A bowyer is a master-craftsman who makes bows. Though this was once a widespread profession, the importance of bowyers and of bows was diminished by the introduction of gunpowder weaponry. However, the trade has survived and many bowyers continue to produce high-end bows. History Historically, a wide variety of bows have been produced for purposes ranging from food gathering and warfare to recreation. Who created these bows depended mainly on the type of bow being produced, but also on the quantity required. The skills required tend to divide traditional bowyers into two groups: Makers of self bows In clans or social groups that used wooden self bows (bows made entirely from one piece of wood) bows would sometimes be crafted by the individual user; however, even with fairly simple bow designs it was often easier to rely upon a few skilled bowyers within the group. By working in groups more could be accomplished. In medieval England, for example, professional bowyers produ ...

Kinetic Energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time. In classical mechanics, the kinetic energy of a non-rotating object of mass ''m'' traveling at a speed ''v'' is \fracmv^2. In relativistic mechanics, this is a good approximation only when ''v'' is much less than the speed of light. The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound. History and etymology The adjective ''kinetic'' has its roots in the Greek word κίνησις ''kinesis'', m ...

Point Shooting
Point shooting, also known as target- or threat-focused shooting, intuitive shooting, instinctive shooting or subconscious tactical shooting, is a practical shooting method where the shooter points a ranged weapon (typically a revolver or semiautomatic pistol) at a target without relying on the use of sights to aim. Emphasis is placed on fast draw and trying to score preemptive hits first. In close quarters combat, where life-threatening situations emerge very quickly, sighted marksmanship techniques become risky, so advocates of point shooting emphasize a less sighting-oriented style that prioritizes the tactical advantages of quick fire superiority and suppression. Point shooting is also a technique used by trained archers and marksmen to improve general accuracy when using a bow, crossbow, firearm or other ranged weapon. By developing a muscle memory for a given weapon, the shooter can become so accustomed to the weapon's weight and balance in its typical shooting position a ...

Elastic Energy
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner. Elasticity theory primarily develops formalisms for the mechanics of solid bodies and materials. (Note however, the work done by a stretched rubber band is not an example of elastic energy. It is an example of entropic elasticity.) The elastic potential energy equation is used in calculations of positions of mechanical equilibrium. The energy is potential as it will be converted into other forms of energy, such as kinetic energy and sound energy, when the object is allowed to return to its original shape (reformation) by its elasticity. U = \frac 1 2 k\, \Delta x^2 The essence of elasticity is reversibility. Forces applied to an elastic material transfer energy into the material which, ...
