Key Concepts

Einstein's Mass-Energy Equivalence

Einstein's mass-energy equivalence, expressed by the equation E = mc², explains the relationship between mass and energy. This principle indicates that the energy released in a nuclear reaction can be calculated by multiplying the mass defect by the square of the speed of light, thereby showing how a small loss in mass results in a large amount of energy.

Mass Defect

Mass defect is the difference between the mass of reactants and the mass of products in a nuclear reaction. It represents the tiny amount of mass that is converted into energy during the reaction, which is a central idea in understanding how energy is released in nuclear processes.
