topic	components
Atomic structure	describe the structure of atoms and ions in terms of protons, electrons and neutrons. state the relative charge and relative mass of a proton, an electron and a neutron.	√ √	√		√
Momentum and circular motion	describe some examples of circular motion, from atomic physics and from planetary motion. recall that an object moving in a circle requires a force and that this force acts towards the centre of the circle. recall that if this force is removed the object will fly off at a tangent to the circle.	√ √ √		√ √ √	√ √ √
Gravitation	understand that gravitational force acts towards the centre of every astronomical object understand that gravitational forces act between all masses and know that the magnitude diminishes with distance and increases with mass.		√√ √√
Galaxy Universe	recall that the Universe is made up of innumerable galaxies. A galaxy is a vast number of star systems held by gravitational forces. The Milky Way is the galaxy which contains our solar system.	√√	√
Big Bang and steady state	describe the Big Bang and steady state model for the formation of the universe.	√√	√√	√
Stars	describe how stars are formed (the life cycle of stars is not required).	√	√
