Energy Transformation Quiz

What is potential energy?

• Energy an object has because of its motion

• Energy an object has because of its position, condition, or chemical composition

• Energy that is always in motion

• Energy that cannot be transformed

In the pogo stick example, what happens when the spring is compressed?

• It stores energy as kinetic energy

• It stores energy as elastic potential energy

• It releases energy as heat

• It loses energy

What type of energy transformation occurs as people jump on pogo sticks?

• Electrical to thermal energy

• Chemical to electrical energy

• Kinetic to potential energy and back

• Thermal to kinetic energy

What happens when the spring in a pogo stick reaches maximum compression?

• Minimum elastic potential energy

• Maximum elastic potential energy

• Energy enters the system

• Energy leaves the system

What is the role of the person in the pogo stick system?

• The person absorbs energy from the spring

• The person transfers energy to the pogo stick system

• The person does not affect the energy in the system

• The person only uses kinetic energy

What is energy transformation?

• The process of energy staying within a system without changing form.

• The process of energy being added to a system without any change.

• The process of energy changing from one form to another.

• The process of energy being removed from a system without any change.

What type of energy does a glass sitting on a table have?

• Kinetic energy

What happens to the potential energy of a glass when it is bumped and starts to move?

• It remains the same.

• It transforms into thermal energy.

• It transforms into kinetic energy.

• It transforms into chemical energy.

What is a field in the context of potential energy?
