Billy is clapping his hands. Every time he moves his hands together he is expending mechanical energy. This type of energy is described by which item on the list below?

• Energy created by the motion and position of an object.
• Energy generated by the sun.
• Energy that flows through a circuit.

Which of the following is the best example of solar energy being used?

• driving a nail into a board with a hammer
• starting a fire with a magnifying glass instead of
  matches
• causing vinegar to fizz by adding baking soda
• using a vacuum cleaner that is plugged into the wall

Potential energy is transformed into kinetic
energy in which of the following scenarios?

• B
• C
• D
• E

By plugging in the stove in scenario D, a
person is hoping to create heat energy from what?

• solar energy
• electrical energy
• mechanical
• chemical

In all of the energy transformations shown
above, the total amount of energy:

• disappeared when it transformed into another type
  of energy.
• decreased when it transformed into another type of
  energy.
• remained the same when it transformed into
  another type of energy.
