A student plugs in an electric fan and the blades begin to spin. This is a direct example of which energy transformation?

Chemical energy to electrical energy

Thermal energy to kinetic energy

Electrical energy to kinetic energy

Kinetic energy to electrical energy

According to the principles of energy transformation, what is happening when energy flows through a system like a powered speaker?

The energy is being permanently stored within the speaker's components.

The total amount of energy in the universe is decreasing.

The energy's form is changing from electrical to sound.

The energy is being used up and disappears completely.

Electrical energy to light energy

Chemical energy to sound energy

Kinetic energy to thermal energy

Thermal energy to electrical energy

To store electrical energy for long-term future use.

To convert electrical energy into other useful forms like motion or sound.

To produce new electrical energy from mechanical parts.

To completely eliminate energy, leaving none behind after use.
