100
Burning a candle.
Chemical energy -> heat energy + light energy
100
What is the process of saving up or storing energy?
Potential energy.
100
Energy that has the ability to fall; this type of energy increases the higher up you go.
Gravitational potential energy.
100
Energy is defined as _________.
The ability to do work.
100

A phone battery stores energy that gets used to power the screen.

What is chemical energy (converted to electrical and light/heat energy)?

200
Using a hot plate to boil water.
Electrical energy -> heat energy
200
What is the process of spending energy or energy in motion.
Kinetic energy.
200
"You can burn it or you can eat it."
Chemical energy.
200
List the renewable resources (list at least 3 out of the 5 possibilities.)
Biomass, hydropower, geothermal, wind and solar.
200

A swinging pendulum has the most of this type of energy at the top of its swing, and the most of this other type at the bottom.

What are potential energy (top) and kinetic energy (bottom)?

300
A hungry football player eating a large sandwich to use the food for energy.
Chemical energy -> mechanical energy
300
A heavy vase on a table has this type of energy.
(Gravitational) potential energy.
300
This type of energy is generated by a force - a push or a pull.
Mechanical energy.
300
List the Non-Renewable resources (list at least 3 out of the 5 possibilities.)
Petroleum, coal, natural gas, uranium and propane.
300

Rubbing your hands together makes them warm. This energy transformation is happening.

What is mechanical energy → heat (thermal) energy?

400
Using a solar-powered calculator.
Radiant energy -> electrical energy ->light energy
400
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
400

This type of energy is stored in the nucleus of an atom and is released during nuclear reactions like fusion in the sun or fission in power plants.

What is nuclear energy?

400
Define gravity.
The force of attraction between all objects in the universe.
400

A roller coaster car slows down as it climbs the next hill, but it still makes it to the top. Explain why, using the Law of Conservation of Energy.

What is: kinetic energy is converted back into potential energy as the car rises — energy isn't lost, it just changes form (with some lost to friction as heat)?

500
A solar panel on the roof of a building used to heat and cool the building.
Radiant energy -> electrical energy
500
A person that has just jumped from an airplane has this type of energy. (2 types)
(Gravitational) potential and kinetic energy.
500
The sun is an example of this type of energy.
Heat, Radiant, Nuclear and Gravitational
500
List the Law of Conservation of Energy.
Energy can be not be created or destroyed.
500

A wind turbine powers a light bulb. Name the complete energy transformation chain.

What is kinetic (mechanical) energy of wind → electrical energy → light energy (+ heat energy)?
