Ballistics can be studied using high-speed photography or high-speed cameras. A photo of a Smith & Wesson revolver firing, taken with an ultra high speed air-gap flash. Using this sub-microsecond flash, the bullet can be imaged without motion blur. Ballistics is often broken down into the following four categories: [23]
Fictional rayguns are often depicted in science fiction.. Strange and exotic weapons are a recurring feature in science fiction.In some cases, weapons first introduced in science fiction have been made a reality; other science-fiction weapons remain purely fictional, and are often beyond the realms of known physical possibility.
Lightsabers can also deflect blaster bolts, allowing a wielder with Jedi reflexes to turn an enemy's own gunfire against them. An active lightsaber gives off a distinctive hum, which rises in pitch and volume as the blade is moved rapidly through the air. Bringing the blade into contact with another lightsaber's blade produces a loud crackle.
Lead bullet being supported by a wooden cup sabot in a Delvigne gun. A cup sabot supports the base and rear end of a projectile, and the cup material alone can provide both structural support and barrel obturation. When the sabot and projectile exit the muzzle of the gun, air pressure alone on the sabot forces the sabot to release the projectile.
Since the mass of the bullet is much less than that of the shooter there is more kinetic energy transferred to the bullet than to the shooter. Once discharged from the weapon, the bullet's energy decays throughout its flight, until the remainder is dissipated by colliding with a target (e.g. deforming the bullet and target).
Sectional density is a very important aspect of a projectile or bullet, and is for a round projectile like a bullet the ratio of frontal surface area (half the bullet diameter squared, times pi) to bullet mass. Since, for a given bullet shape, frontal surface increases as the square of the calibre, and mass increases as the cube of the diameter ...
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
A bullet, while moving through its barrel, is being pushed forward by the gas expanding behind it. This gas was created following the trigger being pulled, causing the firing pin to strike the primer , which in turn ignited the solid propellant packed inside the bullet cartridge , making it combust while situated in the chamber .
