Amount of Energy from Bullet fired from different weapon

  1. Apr 25, 2012 #1
    How we differentiate the amount of Energy of a bullet fired by a gun and a rifle with same linear velocity?

    do they posses the same energy ? or rifle has more energy than gun.

    The energy of the bullet would be E = ½·m·v²

    So for the same m and v the energy would be equal, regardless of how the bullet was fired.

    hi abrowaqas! :smile:
    the rifle bullet will have very slightly more energy, since it will also have rotational energy

    it travels further (and is more accurate) not because of its energy, but because it tumbles less than the gun bullet, and so has less air resistance :wink:
