What is nuclear fission and what is nuclear fusion? In this video, we explain the differences and similarities between nuclear fission and nuclear fusion in simple words — from how fission splits heavy atoms like uranium-235 to release energy, to how fusion combines hydrogen isotopes under extreme heat and pressure to power the Sun. Learn how nuclear reactors work, what chain reactions are, and why fusion produces 3-5x more energy than fission.

Whether you're a physics student, preparing for an exam, or curious about the future of clean energy, this beginner-friendly animated explainer breaks it all down.
