  2. Ballistic pendulum - Wikipedia

    en.wikipedia.org/wiki/Ballistic_pendulum

    A green ballistic pendulum Animation of a ballistic pendulum. A ballistic pendulum is a device for measuring a bullet's momentum, from which it is possible to calculate the velocity and kinetic energy. Ballistic pendulums have been largely rendered obsolete by modern chronographs, which allow direct measurement of the projectile velocity.

  3. Thompson–LaGarde Tests - Wikipedia

    en.wikipedia.org/wiki/Thompson–LaGarde_Tests

    The Thompson–LaGarde Tests have since been criticized as being "highly unscientific" and producing a recommendation unsupported by the test results. [7] Others, notably Julian Hatcher [9] and Jeff Cooper, [10] regarded the tests as well conducted, and the recommendation as fully supported by the evidence available to the board, and empirical evidence subsequently available concerning ...

  4. Circular error probable - Wikipedia

    en.wikipedia.org/wiki/Circular_error_probable

    CEP is not a good measure of accuracy when this distribution behavior is not met. Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region. Munition samples may not be exactly on target, that is, the mean vector will not be (0,0).

  5. Gun chronograph - Wikipedia

    en.wikipedia.org/wiki/Gun_chronograph

    A ballistic chronograph or gun chronograph is a measuring instrument used to measure the velocity of a projectile in flight, typically fired from a gun or other firearm. The instrument is often useful for tasks such as gauging the utility of a firearm or safety of non-lethal projectiles fired from items such as a paintball gun or BB gun .

  6. Inelastic collision - Wikipedia

    en.wikipedia.org/wiki/Inelastic_collision

    Simple ballistic pendulum problems obey the conservation of kinetic energy only when the block swings to its largest angle. In nuclear physics, an inelastic collision is one in which the incoming particle causes the nucleus it strikes to become excited or to break up.

  8. Gun laying - Wikipedia

    en.wikipedia.org/wiki/Gun_laying

    Robins used the ballistic pendulum to measure projectile velocity in two ways. The first was to attach the gun to the pendulum, and measure the recoil. Since the momentum of the gun is equal to the momentum of the ejecta, and since the projectile was (in those experiments) the large majority of the mass of the ejecta, the velocity of the bullet ...
