  2. Physics of firearms - Wikipedia

    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).

  3. Muzzle velocity - Wikipedia

    en.wikipedia.org/wiki/Muzzle_velocity

    For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...

    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]

  5. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    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 ...

    Characters can be seen escaping, or even dodging those bolts, and the blaster bolts themselves can be seen flying at a moderate-fast speed. Dodging a laser bolt would be nearly impossible, as it would travel at the speed of light. [5] Due to that, it is reasonable the blaster fire would pass like a sparkle, and hit its target.

  7. Hypersonic speed - Wikipedia

    en.wikipedia.org/wiki/Hypersonic_speed

    Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.

    The standard lightsaber is a sword-like weapon that emits a blade of pure energy from its metal hilt which has no mass but can cut through almost anything and deflect blaster bolts. [39] The core of the lightsaber is a kyber crystal , which according to Star Wars canon acts as the focusing element and takes on a specific color when it "bonds ...

  9. Terminal ballistics - Wikipedia

    en.wikipedia.org/wiki/Terminal_ballistics

    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]
