second formula with s L j .

Piston current em piston I versus mechanical collision piston v is l per s. Force current piston Fi is Fi=qvb  v=c= speed of light b = magnetic field q=I/c because I=QC so Fi=I/c)*c*B=i/v)*c*B ==I*B Fi=-Fmech= mechanical force =mv/t=mdx/dt^2=mdL/ds^2 Ei=currents energy=Fi*x=-Fmech*x=-Emech Pi= currents power=dEi/dt=dEmech/dt  = mechanical power dPi/dt^n= power velocity derivatives to nth derivative=-dPmech/dt^n = mechanical power derivatives so every person can have a power derivative named after them as a natural unit if n equals their Iban then the derivative to their iban is their power and energy plus one as their unit. Fi=I*B*kasa8=-Fmech =m*L/s^2 in diced order s^-2)=(L^-1)*j*B*kasa8/m by PhD Alborz Seddigh Afshar
