Energy Transformations

Energy Transformations

Law of Conservation of Energy

states that energy cannot be created or destroyed, it can only change forms.

Energy Transformation

is the process of energy changing from one form to another.

Released during chemical reactions​

Chemical Energy

The movement of electrical charges usually through wires​

Electrical Energy​

​

The energy of the movement of particles in an object. ​

Thermal Energy

The total potential and kinetic energy. ​

Mechanical Energy

The transfer or movement of heat without matter to carry it

Radiant Energy​

​

Vibrations that can be heard.​

Sound Energy

​

​The energy in the nucleus, or core, of an atom.

Nuclear Energy

​
