Energy and Its Transformations Quiz

A book is sitting on a high shelf. What kind of energy does it have?

• Energy of motion

• Stored energy due to position

• Energy released during a chemical reaction

• The rate of doing work

When lifting a box off the ground, what is the unit of work done on the box?

• Newton (N)

• Joule (J)

• Watt (W)

• Meter (m)

If a wind turbine generates 100 Joules of energy in 5 seconds, what is its power output?

• 20 Watts

• 500 Watts

• 5 Watts

• 105 Watts

What happens to solar energy when it is used to power a solar panel?

• Solar energy is destroyed

• New energy is created from nothing

• Solar energy changes from one form to another

• Solar energy remains the same without any change

Imagine a roller coaster at the top of its track. What kind of energy is being demonstrated?

• The sum of potential and kinetic energy

• The energy stored in chemical bonds

• The energy due to the roller coaster's motion only

• The energy due to the roller coaster's position only

At what point does a ball thrown upwards have the highest potential energy?

• Just before it starts falling back down

• Halfway down when it is falling back to the ground

• The moment it starts moving upwards

• When it hits the ground

At what point does a ball thrown upwards have the highest kinetic energy?

• Just before it starts falling

• Halfway down when falling

• The moment it starts moving upwards

• Just before it hits the ground

When a roller coaster is at the top of its track, it has maximum potential energy. As it descends, the potential energy is converted into kinetic energy. What does this scenario illustrate about the law of conservation of energy?

• Energy can be created and destroyed

• Energy can neither be created nor destroyed, only transformed

• Energy is always lost when work is done

• Energy can be transformed into matter

When you eat an apple, what type of energy is your body storing from it?

• Kinetic energy

• Potential energy

• Chemical energy

• Mechanical energy
