Energy Transformations

• Chemical

• ​Sound

• Electrical

• Radiant/Light

• Mechanical

• Thermal

• Nuclear

The law states: Energy cannot be created nor destroyed.

​

​

In other words...

Energy can only change its forms from one type to another.

​

The energy of the world is constant because of the total amount of energy does not change.

You may also hear it referred to as Energy conversions

Electrical (plugging it in) --> Mechanical (spinning of the fan)--> Heat (hot air)

• It runs on batteries (chemical energy)

• When it turns on, it's changed from chemical into electrical

• Then, it is transformed into light energy.

Chemical --> Heat --> Mechanical

Electrical --> Mechanical --> Heat

Electrical --> Thermal

Kinetic --> Mechanical --> Electrical

• If you have to plug it in ........ conversions likely starts with electricity

• If it is battery powered..... first 2 steps are chemical --> electrical

• If it produces electricity......... last step is likely electrical
