What is the difference between nuclear fusion and nuclear fission?
This is a common question in A-level physics and a core concept for the course.
Fission occurs when a heavy nucleus splits into smaller, more stable nuclei, releasing energy in the process.
Fusion occurs when light nuclei fuse together to form a heavier nucleus. This also involves a release of energy.
