Jake and Emma are observing a fan in their classroom. The fan has a motor that converts electrical energy into another form of energy that propels the fan blades.

Into which form of energy is electrical energy converted in a fan?

• heat

• light

• mechanical

• sound

Brock and Emma wrap a metal sheet around a copper wire. They then hammer the metal sheet several times. The temperature of the sheet rises, and it becomes even more flat. Which type of energy transformation does the example involve?
