What type of energy is produced from nuclear fission?

Nuclear fission generates energy primarily through the kinetic energy of fission fragments. In the process of fission, a heavy nucleus splits into two or more smaller nuclei, known as fission fragments. This splitting releases a significant amount of energy, mainly in the form of kinetic energy. The fission fragments move apart at high speeds, and this motion contributes to the overall energy produced.

Additionally, this kinetic energy can be transformed into thermal energy when the fragments collide with other atoms. However, the foundational energy release during fission is directly associated with the kinetic energy of these fragments. This released energy is what powers nuclear reactors and is harnessed in various applications, making it the primary focus when discussing the type of energy produced from nuclear fission.

Other options do not capture the primary energy transformation taking place during fission. While nuclear reactions can produce thermal energy eventually, the initial energy release is due to the kinetic motion of the fission products.
