Physics

Mass-Energy and Nuclear Binding Energy

द्रव्यमान-ऊर्जा और नाभिकीय बंधन ऊर्जा

In Class 12 Physics, this topic from Chapter 13: Nuclei explains how mass can be converted into energy through Einstein’s mass–energy relation, E = mc². Students learn the meaning of mass defect and nuclear binding energy, calculate binding energy from the mass difference between a nucleus and its separate nucleons, and interpret binding energy per nucleon as an indicator of nuclear stability. The topic also connects these ideas with energy release in nuclear fission and fusion.
