This document defines and provides brief descriptions of six different forms of energy: mechanical, electrical, light, thermal, sound, and chemical energy. Mechanical energy includes both kinetic and potential energy. Electrical energy is produced by electron movement. Light energy travels in waves, even through empty space. Thermal energy is the energy of moving particles and is also called heat energy. Sound energy comes from vibrating objects. An example of transforming chemical energy is a car engine, which changes the chemical potential energy in gasoline into kinetic motion energy.

1. Conversion of
Energy

2. Mechanical Energy
The energy of movement. This energy
includes both kinetic energy (motion)
and potential (stored) energy

3. Electrical Energy
A form of energy that is produced
when electrons move from one place
to another place

4. Light Energy
A form of energy that travels
in waves and can move through
empty space where there is no
air.

5. Thermal Energy
The energy of moving
particles in a substance;
also called heat energy

6. Sound Energy
A form of energy produced
by vibrating objects.

7. Changing forms of Energy
• An example of transforming chemical energy is a car engine.
Chemical potential energy in gasoline is transformed into kinetic
energy of the car as it moves!!
