What kind of energy is being shown in the picture?

• Light

• Gravitational

• Potential

• Kinetic

Which is the best example of kinetic energy?

• A car sitting on top of a hill

• A skateboard on the sidewalk

• A wagon rolling down a hill

• A powerwheel parked in the yard

Which two types of energy are seen in a roller coaster?

• Kinetic & Potential

• Potential & Light

• Kinetic & Thermal

• Kinetic & Chemical

Which is NOT true regarding energy?

• Energy can be changed

• Energy can be converted

• Energy can be transferred

• Energy can be created

Why does rubbing your hands together help warm them?

• heat is transferred back and forth between two hands

• heat is absorbed by the hands from the air

• heat is conducted between two hands when they are touching

• heat is generated by mechanical energy being converted to heat energy

In the magical world of an oven, what kind of energy transformation takes place? Electrical energy turns into _____ energy!

• Thermal

• Solar

• Electrical

• None

Energy cannot be created nor destroyed; it can only change forms.

• true

• false

Which type of energy transformation occurs when a flashlight shines?

• chemical → thermal → electrical
• chemical → electrical → light
• thermal → chemical → light
• chemical → electrical → chemical

The Theory of the Conservation of Energy states -

• Energy can be created, just not destroyed. It changes its form from one type to another.
• Energy can never be created nor destroyed. It can only change its form from one type to another.
• The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.
• Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.

Energy transformations occur when...

• energy is created through conduction
• energy changes from one form to another
• two forces slide together that are touching
• a chemical reaction takes place
