Physics - Fizik

The energy we receive from the Sun is called solar energy. It consists mainly of light and heat that travel through space. These forms of energy come from atoms smashing into each other in the centre of the Sun and joining together, or fusing. This process is called nuclear fusion as we study in form 5. Energy thar comes from the centres or nuclei of atoms is called nuclear energy. The form of nuclear energy in nuclear power stations here on Earth comes from nuclear fission, when atoms split apart.
