Energy Quiz for Grade 6

What are the different types of potential energy?

• Chemical, electrical, sound, and thermal potential energy

• Kinetic, thermal, electrical, and sound potential energy

• Gravitational, elastic, chemical, and nuclear potential energy

• Light, magnetic, sound, and nuclear potential energy

List three forms of kinetic energy.

• Potential, electrical, chemical

• Magnetic, elastic, nuclear

• Mechanical, thermal, radiant

• Sound, nuclear, gravitational

Explain the process of potential energy transforming into kinetic energy with an example.

• Potential energy transforms into sound energy when an object is dropped from a height.

• Potential energy transforms into light energy when a light bulb is turned on.

• When a roller coaster car is at the top of a hill, it has potential energy. As it goes down the hill, the potential energy is transformed into kinetic energy.

• When a roller coaster car is at the top of a hill, it has kinetic energy. As it goes down the hill, the kinetic energy is transformed into potential energy.

What is energy transformation? Provide an example.

• Energy transformation is the process of changing energy into matter. For example, when a light bulb transforms electrical energy into light energy.

• Energy transformation is the process of changing matter into energy. For example, when a car burns gasoline to produce motion.

• Energy transformation is the process of changing one form of matter into another. For example, when a wind turbine transforms wind energy into electrical energy.

• Energy transformation is the process of changing one form of energy into another. For example, when a toaster transforms electrical energy into thermal energy to toast bread.

State the law of conservation of energy.

• Energy is only conserved in living organisms

• Energy can be transformed into matter

• Energy can be created and destroyed at will

• Energy cannot be created or destroyed, only transformed from one form to another.

Give an example of sound energy.

• The sound of a ringing bell

• The color of a rainbow

• The taste of chocolate

• The smell of a flower

What is electromagnetic energy and provide an example of it.

• Heat from a fire

• Visible light

• Static electricity

• Sound waves

Explain how potential energy and kinetic energy are related.

• Potential energy can only be converted into heat energy

• Kinetic energy can never be converted into potential energy

• Potential energy and kinetic energy are completely unrelated

• Potential energy can be converted into kinetic energy and vice versa.

Describe how energy is conserved in a roller coaster ride.

• Potential energy is converted to kinetic energy and vice versa as the coaster moves

• The roller coaster gains energy from the passengers

• The roller coaster absorbs energy from the environment

• The roller coaster loses energy as it moves

How does a wind turbine convert kinetic energy into electrical energy?

• By using water to generate steam and turn a turbine

• By using the rotation of the blades to spin a generator

• By using solar panels to capture sunlight

• By using magnets to create electrical currents
