Nuclear Fission sim
... Why do fission and fusion produce so much energy? • In nuclear reactions, energy comes from converting tiny amounts of mass lost when the bonds between protons and neutrons are broken and made. These bonds are due to the strong force. • The strong force is a thousand times stronger than the electri ...
