Burning a candle.

Chemical energy -> heat energy + light energy

100

What is the source of almost all of the energy on the Earth?

The sun

100

What is the energy an object gets from its position?

Potential energy.

100

Energy that has the ability to fall; this type of energy increases the higher up you go.

Gravitational energy.

100

Define sound energy

Vibration

200
Using a hot plate to boil water.
Electrical energy -> heat energy

Why are fossil fuels nonrenewable?

It takes millions of years to form fossil fuels.

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.

300
A hungry football player eating a large sandwhich to use the food for energy.
Chemical energy -> mechanical energy
300

Why is nuclear energy nonrenewable?

It uses Uranium, which is a metal that is mined.  Someday we will run out of Uranium.

300

Which has more gravitational potential energy?

A skier at the top of a hill

A bowling ball in an airplane 1 mile up in the air

A book on a shelf

A bowling ball in an airplane 1 mile up in the air

300

This type of energy is generated by a force - a push or a pull- and puts objects in motion

Mechanical energy.

300

List the Non-Renewable resources (list at least 3 out of the 5 possibilities.)

Petroleum, coal, natural gas, uranium and propane.

400
Using a solar-powered calculator.
Radiant energy -> electrical energy ->light energy
400

Name one way you can conserve energy in your home.

Energy efficient appliances, turn your heat down/air conditioning up, insulate your home, turn out lights when not in use....

400

A person running down the sidewalk has this type of energy.

(Mechanical) kinetic energy.

400

An atom splitting is this type of energy.

Nuclear energy.

400

What does it mean when we say an energy resource is "inexhaustible"?

It will never run out.

500
A solar panel on the roof of a building used to heat and cool the building.
Radiant energy -> electrical energy
500

What is one of the "cons" of using fossil fuels (other than they will one day run out).

They produce CO2 when burned, increasing air pollution.

500

Which has the most kinetic energy?

A boulder at the top of a cliff

A sprinter running over the finish line

A bulldozer rolling down a steep incline


.A bulldozer rolling down a steep incline

500

The sun is an example of this type of energy.

Heat, Radiant, Nuclear 


500

What is the Law of Conservation of Energy.

Energy can be not be created or destroyed.
