Choose a topic
Energy stores and transfers
Identify where energy is stored and explain mechanical, electrical, heating and wave transfers.
Kinetic and gravitational energy
Calculate energy from mass, speed and vertical height, with the reference and assumptions stated.
Work and conservation of energy
Calculate work done by a force and account for energy changes, including transfers to the surroundings.
Power and measurements
Distinguish energy from its transfer rate and determine average power from measurements.
