Presentation transcript:

Baseline (Aiming for 4): State the factors that affect the size of an elastic potential and a kinetic energy store. Further (Aiming for 6): Calculate the elastic potential of a spring and the kinetic energy of an object launched from it. Challenge (Aiming for 8): Perform calculations involving the rearrangement of the kinetic and elastic potential energy equations.
