When a fan is turned on, it changes electrical energy into energy.
a. motion
b. magnetic
c. gravitational
d. electromagnetic

When the fan is running, it causes air to move.  Think about it:  Air that was
not moving a few moments ago starts moving, so it must have gotten a kick
of energy from somewhere.  That's the energy that started out at the power-
plant as nuclear energy in a uranium rod or chemical energy in a lump of coal,
moved from the power-generating plant to your house as electrical energy, and
made the fan spin.  Finally, it ended up as 'kinetic' energy of moving air.

Less force and energy was applied
