Final Review Units 5-6

Match the following images with the best energy transfer type

• Gravitational to Kinetic

• 
• Radiant to Electrical

• 
• Nuclear to Radiant

• 
• Chemical to Kinetic

• 
• Radiant to Chemical

• 

Answer explanation

This question links to success criteria: I can identify common energy transformations from one type to another.

If you got it correct place a check mark in the question results section. If you got it incorrect place an X in that section. If this was a redemption question, cross out the one X and replace it with a check mark.

Is Nuclear Power a renewable energy source, why or why not?

• Yes, nuclear energy is renewable so nuclear power must be too.

• No, nuclear energy is not renewable so nuclear power cannot be either.

• No, nuclear energy is renewable but the Uranium we use in power plants to access it is not.

• Yes, matter cannot be destroyed so there will always be nuclear energy.

Answer explanation

This question links to success criteria: I can differentiate renewable and nonrenewable energy sources.
