What is the law that states energy cannot be created or destroyed?

• Law of Thermodynamics

• Law of Conservation of Energy

• Law of Energy Efficiency

• Law of Energy Transformation

What happens to some energy during a transformation?

• It is completely destroyed

• It is always converted to light

• Some is lost as heat

• It becomes more efficient

In the example of a car engine, what type of energy is transformed into mechanical energy?

• Electrical energy

• Light energy

• Chemical energy

• Potential energy

What type of energy does a roller coaster have at the top of a hill?

• Kinetic energy

• Thermal energy

• Potential energy

• Chemical energy

Why is understanding energy transformations important?

• It helps us create more energy

• It helps us appreciate energy flow and changes

• It allows us to destroy energy

• It makes energy transformations 100% efficient
