The document discusses the two main forms of energy: potential energy and kinetic energy. It provides examples of each type and explains that a pendulum demonstrates both as it swings back and forth, changing from potential to kinetic energy. The document also discusses solar energy and the three ways heat is transferred: conduction, convection, and radiation. Quizzes are included to test the reader's understanding.

6. The Powerful Sun
The sun is vital for life on
earth. It provides us with
solar energy. This energy is
a result of nuclear reactions.
HEAT + LIGHT = Solar Energy

12. Heat Transfer
Heat is transferred from
warm to cool places. The
heat energy in this cup of hot
coffee moves from the hot
coffee to the cup, to the
counter it’s sitting on and
also to the cool air
surrounding it. This transfer
of heat causes the coffee to
cool down.

13. Quiz:
What is the correct order of heat transfer
for this situation?
Fire to air to pizza to grill
Pizza to grill to air to fire
Air to fire to grill to pizza
Fire to grill to pizza to air
