Energy Transformations
Provide an example of CHEMICAL ENERGY -> HEAT ENERGY + LIGHT ENERGY.
Burning a candle.
1 Newton-meter = 1 kg/m/s2 = __________.
Joule.
What is the process of saving up or storing energy?
Potential energy.
Energy that has the ability to fall; this type of energy increases the higher up you go.
Gravitational energy.
Energy is defined as _________.

Metal is a good CONDUCTOR or INSULATOR of heat.
Good conductor.
What is the process of spending energy or energy in motion?
Kinetic energy.
The energy in batteries is stored as this form of energy.
Chemical energy.
List the renewable resources (list at least 3 out of the 5 possibilities.)
Biomass, hydropower, geothermal, wind and solar.
What is a Joule, and why do we use it?
Unit of energy (easier than Nm or kg/m/s2!)
