Energy Transformation Quiz

What does the law of conservation of energy state?

• Energy can only be transformed from one form to another.

• Energy is always lost in transformations.

• Energy is only found in living organisms.

• Energy can be created and destroyed.

When you eat breakfast, what type of energy are you primarily obtaining?

• Kinetic energy

• Heat energy

• Chemical energy

• Sound energy

What happens to the kinetic energy of the balls when they are smacked together?

• It disappears completely.

• It transforms into sound energy.

• It transforms into light energy.

• It remains as kinetic energy.

How is sound energy produced when the balls are smacked together?

• By heating the surrounding air.

• By causing vibrations in the air molecules.

• By changing the color of the balls.

• By creating light waves.

What evidence shows that kinetic energy is transformed into heat energy?

• The balls become larger.

• The paper remains intact.

• The balls change color.

• The paper has burn marks.

What is observed on the aluminum foil when the balls are smacked together?

• Concentric rings appear.

• The foil melts.

• The foil becomes heavier.

• The foil changes color.

What do the concentric rings on the aluminum foil represent?

• A shockwave from the impact.

• A magnetic field.

• A change in temperature.

• A chemical reaction.

Why is a magnifying glass recommended for observing the aluminum foil?

• To change the color of the foil.

• To make the foil heavier.

• To increase the size of the rings.

• To heat the foil.

What should students do with the aluminum foil after the demonstration?

• Throw it away.

• Use it to cook food.

• Explore it with a magnifying glass.

• Paint it.

What is the purpose of using a magnifying glass in the demonstration?

• To create more sound.

• To better observe the energy transformations.

• To change the color of the paper.

• To make the balls move faster.
