a branch of physics that studies the structure of the atomic nucleus, the processes of radioactive decay, and the mechanism of nuclear reactions. The meaning of the term is frequently expanded to include the physics of elementary particles as well. Sometimes areas of research that have become independent branches of technology, such as accelerator technology and nuclear power industry, continue to be considered as branches of nuclear physics.
What is nuclear energy. Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particles that can break a material. At the core of each atom there are two types of particles (neutrons and protons) that are held together. Nuclear energy is the energy that holds neutrons and protons. Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this.
