Question

what is self energy​

Answer 1

Answer:

In most theoretical physics such as quantum field theory, the energy that a particle has as a result of changes that it itself causes in its environment defines self-energy. , and represents the contribution to the particle's energy, or effective mass, due to interactions between the particle and its system.

Answer 2

Answer:

Self energy is internal energy of the body but interaction energy comes when two body interacts. But internal energy itself is due to the interaction between entities (fundamental particles, atoms, molecules,ions) inside the same body. So it becomes difficult to classify between self energy and interaction energy.
