3. Changing Forms
of Energy
Chemical, thermal, radiant, and electrical are some of
the forms that energy can have. In the world around
you, energy is transforming continually between one
form and another. You observe some of these
transformations by noticing a change in your
environment.

4. The Law of Conservation of Energy
The law of conservation of energy states
that energy cannot be destroyed but can be
transformed into another form and used for
energy purposes. The science that studies
energy changes from one to another is the
science of energy conversion.

5. The ability to transform energy allows
the biker to climb the hill.
As the mountain biker pedals, his leg muscles
transform chemical energy into kinetic energy. The
kinetic energy of his leg muscles transforms into
kinetic energy of the bicycle as he pedals. Some of this
energy transforms into potential energy as he moves
up the hill.

6. Changing Kinetic
and Potential
Energy
During the flight of the baseball, energy is transforming
between kinetic and potential energy.

8. Transforming Chemical Energy
The transformation of chemical to
kinetic energy occurs in muscle
cells. There, chemical reactions take
place that cause certain molecules
to change shape. Your muscle
contracts when many of these
changes occur, and a part of your
body moves.

9. Transforming Electrical Energy
The simple act of listening to a radio involves many
energy transformations. A few are diagrammed here.

10. Transforming Thermal Energy
Thermal energy moves from
the hot chocolate to the
cooler surroundings.

11. How Thermal Energy Moves
Thermal energy can move from one place to another.
Thermal energy only moves from something at a higher
temperature to something at a lower temperature.

12. Generating Electrical Energy
A coal-
burning
power plant
transforms
the chemical
energy in
coal into
electrical
energy.
