Separate only AQA Edexcel OCR 8.2 The life cycle of a star The life cycle of a star from nebula to protostar, main sequence, red giant and white dwarf, and for massive stars, red supergiant, supernova, neutron star or black hole, and how elements are made. For Separate Science. Separate only AQA Edexcel OCR 8.3 Orbits and satellites How gravity provides the force for circular orbits, why the speed is constant but the velocity changes, why smaller orbits need higher speeds, and natural and artificial satellites.
