Harnessing Human Energy Retake Assessment

A student walking is an example of which type of energy?

• Potential Energy
• Thermal Energy
• Kinetic Energy
• Situational Energy

A stretched balloon or rubber band has which type of energy?

• Potential Energy
• Thermal Energy
• Kinetic Energy
• Situational Energy

Look at this graph, which has the most energy output, and how do you know?

• Nuclear Power- it is created by energy from uranium.
• Wind Turbines- it is natural energy that is around us all the time.
• Nuclear Power- it has the tallest bar on the graph.
• Human Powered Energy- it has the shortest bar on the graph.

How are potential energy and kinetic energy related in a system?

• Energy can't be created or destroyed, they are not related.
• One is chemical and one is physical.
• As potential energy decreases, kinetic energy increases.
• As potential energy increases, kinetic energy also increases.

Out of the choices given, where does the roller coaster most likely have the most Potential Energy?

• Point C
• Point D
• Point E
• Point F

Out of the choices given, where does the roller coaster most likely have the most increase of Kinetic Energy?

• From B to C
• From C to D
• Point E
• Point F

Choose the answer that best describes the diagram.

• The flywheel creates energy, transferring to the generator, which transfers energy to the battery, and that energy makes the light shine.
• The crank creates energy that moves the flywheel, transferring to the generator, which transfers energy to the battery, and that energy makes the light shine.
• Potential energy from the flywheel moving is being transferred to the generator, which creates energy in the battery, and that energy makes the light shine.
• Kinetic energy from the flywheel moving is being transferred to the generator, which transfers energy to the battery, and that energy makes the light shine.

Which statement is most correct about energy?

• Energy can be transferred, but never converted.
• Potential Energy is created and Kinetic Energy is the energy of movement.
• Energy cannot be created or destroyed.
• Kinetic Energy is created when it is transferred from Potential Energy.

`A rescue worker wants to have an emergency back up system, in case he runs out of electricity. Which answer best describes what can happen?

• They can use a hand crank, kinetic energy from turning the crank will be converted to electrical energy which can power lights.
• They can use a hand crank to create potential energy, which powers lights.
• There is no way to have power without electricity.
• They can use a hand crank to create thermal energy, which will power lights.

Which pieces of Evidence support Claim 2?

• Evidence 2, 4, 6
• Evidence 1, 3
• All the evidence supports Claim 1.
• There is no way to tell if these pieces of evidence support or refute the claim.
