Marking points
B1 · 1 mark · One correct transfer named (e.g. gravitational potential to kinetic)
B2 · 1 mark · A second correct transfer named (e.g. kinetic to sound or heat)
Worked solution
Energy transfers: (1) Gravitational potential energy to kinetic energy as the person falls. (2) Kinetic energy to sound or heat energy when the person hits the water.
