Nuclear Fusion in Stars | GCSE Physics Practice
Nuclear fusion is the joining of two light nuclei to form a heavier nucleus, releasing energy.
Why is nuclear fusion so difficult to achieve on Earth?
What is Nuclear Fusion in Stars | Practice?
"A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy."
Which type of radiation is stopped by a single sheet of paper?
Niels Bohr changed the atomic model by suggesting that electrons ____.
Which type of radiation is an electromagnetic wave?
What is the definition of half-life?
Fusing Atoms
Two light nuclei (e.g. Hydrogen) fuse to form Helium.
Some of the mass is converted into energy (E=mc²).
Requires extremely high temperature and pressure to overcome electrostatic repulsion.
This is the process that powers stars like our Sun.
Comparison Fact: Fusion releases MORE energy per gram of fuel than fission and produces no long-lived radioactive waste.
