Nuclear Fission & Fusion

Nuclear Fission & Fusion. FISSION : a heavy nucleus splits into 2 lighter nuclei. some elements undergo fission spontaneously some elements can be induced to undergo fission when bombarded with other particles (e.g. neutrons). FUSION : 2 nuclei combine to form a heavier nucleus.

Mass-Energy Equivalence

Mass-Energy Equivalence. Mass-Energy Equivalence. The equation E = mc 2 is probably the most recognized symbol of physics. This equation tells us that matter and energy are really two forms of the same thing. Mass-Energy Equivalence.
