Not, they're different.I though momentum is kinetic energy?
Momentum increases are linear. Mass x velocity. If the weight doubles the momentum doubles.
Kinetic energy is exponential. It is calculated by mass x the square of the velocity. If the velocity doubles the energy quadruples.
e.g. a 200 grain bullet at 800 fps has twice the momentum of a 100 grain at 800 fps but a 100 grain bullet at 1600 fps will strike with 4 times the kinetic energy of the same bullet at 800 fps.
