    • Topic 1-Energy
      • Energy stores- thermal, kinetic, gravitational potential, elastic potential, chemical, magnetic, electrostatic and nuclear.
        • Energy can be transferred by doing work.
      • Energy lost from the gravitational potential store= energy gained in the kinetic energy store.
        • Gravitational potential energy(J)= mass x height x gravitational field strength.
      • Movement means energy in an object`s kinetic energy store.
        • Kinetic energy(j)=1/2 x mass x (velocity) squared
      • Raised objects store energy in gravitational potential energy stores.
