True or false: a fan that is not spinning has energy.

• True

• False

True or false: there is potential energy stored in the cord of the fan.

• True

• False

Answer explanation

Electrical cords do not store energy. Energy would transfer through the cord into the fan if the fan was plugged in and turned on, but once you turn the fan off there is NO energy stored in the fan or cord. So the fan not spinning does NOT have potential energy.
