★Here we have :-
E = Energy
m = Mass
c = Speed of light (299,792,458 m/s)
★By work energy principle work is eqivalent to Energy :-
Work = Energy
★As we know that :-
★We may also write it as :-
dE = F × dx
★According to Newton second law of motion :-
Here p is linear momentum hence
dp = mdv + vdm
★Substitute the value of dp in Equation (1)
dE = mvdv + v²dm ...... (2)
★It can be also written as :-
c²dm - v²dm = mvdv
c²dm = mvdv + v²dm ........ (3)
c²dm = dE
∆E = ∆m × c²
