Atomic bomb explosions make a "mushroom cloud" - this is a fission reaction Nuclear physics is the process of getting energy from the nucleus of an atom. There are two ways to release energy from atoms: fission and fusion. Fusion happens all the time in nature, mostly inside stars because fusion needs lots of heat or gravity to get it going. Fusion works with the [...]

Nuclear fusion – Simple Physics

The Sun shining from space Fusion reactions are how the first stars got started. Soon after the Big Bang, hydrogen atoms began bumping into each other and merging into one bigger heliumatom. Four atoms with four nuclei - centers - mixed together into one atom with a bigger nucleus. But each time this happened there was a bit of energy left [...]

Nuclear fission: Atomic bomb explosions make a "mushroom cloud" Fission reactions are the kind of nuclear reaction we use for nuclear power plants and nuclear submarines, and also to set off a nuclear bomb. With fission reactions, you take very large atoms like uranium and plutonium and smash them apart into smaller atoms. Because it takes a [...]
