Nuclear fission occurs when a uranium nucleus splits into two, producing particles with less total mass than the original nucleus because some mass is converted to energy according to Einstein's equation E=Δmc2. This energy released from changes in mass powers nuclear reactors or causes nuclear explosions.

4. • An example of this is when a uranium nucleus splits into
two by a process called nuclear fission. After the uranium
nucleus splits the different particles produced have less
mass than the original uranium nucleus.
• This is because some of the mass has been released as
energy. This energy provides the heat in a nuclear power
station or the explosion for a nuclear weapon. This is an
example of E= Δmc 2
