Energy Transformations Quiz

What is the Law of Conservation of Energy?

• Energy can be created and destroyed but not transformed.

• Energy can neither be created nor destroyed; it can only be transformed from one form to another.

• Energy can be destroyed but not created.

• Energy can be transformed and destroyed but not created.

How does the energy transformation in fossil fuel power plants impact the environment?

• It has no significant impact on the environment.

• It reduces the carbon footprint by converting chemical energy to electrical energy.

• It contributes to air pollution and greenhouse gas emissions by releasing carbon dioxide when burning fossil fuels.

• It increases the amount of renewable energy sources.

Explain how the principle of energy conservation is applied in designing a roller coaster to ensure it completes its course.

• By ensuring the roller coaster has enough initial kinetic energy to reach the end.

• By designing the roller coaster to have its highest point at the beginning, converting potential energy into kinetic energy to move through the course.

• By using motors to continuously add energy to the system.

• By making the track as flat as possible to avoid energy transformations.
