Interesting, henryk, but you'll have to explain that one a bit more in this context.
inertia force in passive\static\ bumper or dampfer \kinetic enrgy conversion into potential\
in case of dynamical dampfer \kinetic energy conservation\ ,M*V^2=J*(omega)^2
i>1 ,in practice up to circa 10...
m/i =effect of inertia mass decreasing.
"a ball screw attached to a heavy disk "
J=0.5 mr^2 \mass and radii\
=ligt flywheel with high rpm...
