[QUOTE="Clark, post: 1303625, member: 6600"] The momentum of the projectile + the momentum of the center of mass of the gas = the momentum of the free recoiling rifle. The kinetic energy of the projectile + the kinetic energy of the gas does not equal the kinetic energy of the free recoiling rifle example : a 30-06 [b]bullet may have 2500 kinetic energy foot pounds[/b] a 30-06 [b]rifle may have 20 kinetic energy foot pounds.[/b] example: a 30-06 bullet and gas may have a momentum of [.025 pounds][3000 fps] = 75 pounds fps a 30-06 rifle may have a momentum of [10 pounds ][ 7.5 fps] = 75 pounds fps The momentum equations look like M1V1 = M2V2 The energy equations look like E = 1/2 mv^2 Because the bullet energy speed is squared, it has much more energy than the rifle recoil, but the same momentum.
