[QUOTE="Elethiomel, post: 3365059, member: 49897"] Heh. No. The momentum isn't *used up* sooner. The momentum has nothing to do with it. The only things that matter with regards to the range before something hits the ground are: - angle of launch - velocity at launch - air resistance and its effects on velocity during flight - gravity The big culprit when it comes to range is velocity. A heavy object goes shorter than a light object with the same kinetic energy not because it has less "momentum left over", but because gravity accelerates everything at the same rate and a slower object will thus cover less ground before it hits the ground. It doesn't "lose energy faster", it "hits the ground sooner", which is a very different thing. I refer you to the post where this originated: To which you replied: The flatness of the trajectory is directly proportional to the speed of the projectile. The energy of the projectile is [i]squarely[/i] proportional to the speed of the projectile. The energy of the projectile is directly proportional to the mass of the projectile. Therefore, a projectile weapon with a flat trajectory and a heavy projectile must, by the laws of physics, deliver more energy to the target than a projectile weapon with an arcing trajectory and a light projectile.
