It's been 40 years since Freshman Physics...it's been 25 years since I took geophysics...for me, the concepts have been reduced to abstractions since I don't use them in my profession...as far as reloading or other applications go, what used to pass for understanding has faded to acceptance. If you really need to understand these concepts, it might not hurt to enroll in an elementary mechanics class. I got rid of my last college physics text some time back.
Remember that the value for kinetic energy changes with velocity. As the velocity changes, the capacity to move weight changes. 1 pound moving at 1 foot per second will have a different kinetic energy value than one pound moving at an inch per second.
Hell, inertial moment is really gonna give you fits.
