Question

A battery powers a circuit for a small noisy fan. The fan’s motor gets warm as it turns. What energy transformations are taking place?

Answer 1

Electric potential energy in the battery transforms to electric energy. Electric energy transforms to motion energy (spinning fan blades), sound energy (noise), and thermal energy (a warm motor).

Answer 2

The battery is an electric energy source, which is being used to power a motor. The motor turns this electricity into kinetic energy as it spins the fan, creates heat from friction, and creates noise as stated by the problem.
