let q=relativistic factor(adsbygoogle = window.adsbygoogle || []).push({});

then F=q*m0*a (where m0 is rest mass and a=acceleration)

if E=m*c^2 =>dE=dm*c^2 (i'm not sure about this)

and dL=F*dx (is the infinitesimal work completed by an external strenght F on the system)

F*dx=dm*c^2 =>

q*m0*a*dx=dm*c^2 => dm/m0=(q*a/c^2)*dx

m'(x)=q*m0*a(x)/c^2 ==> F=m'(x)*c^2 .

a=m'(x)*(c^2/(q*m0))

is right?
