100
Energy cannot be created or destroyed, but can be changed from one form to another.
What is the Law of Conservation of Energy?
100
Energy resources that formed from the buried remains of plants and animals that lived millions of years ago.
What are Fossil Fuels?
100
This energy can travel through a vacuum.
What is Light Energy?
200
This energy is caused by an objects vibrations.
What is Sound Energy?
200
Your body uses this energy to make Kinetic energy.
What is Chemical Energy?
200
A force that opposes motion between two surfaces that are touching.
What is Friction?
200
Energy resources that cannot be replaced or are replaced more slowly than they are used.
What are Nonrenewable Resources?
200
This type of nuclear energy is created in nuclear power plants.
What is (Nuclear) Fission?
300
The kinetic energy due to random motion of the particles that make up an object.
What is Thermal Energy?
300
An energy conversion found in plants.
What is Photosynthesis?
300
A well-defined group of objects that transfer energy to one another.
What is a Closed System?
300
Geothermal Energy is considered this type of resource.
What is Renewable Resource?
300
The unit in which energy is expressed.
What are Joules?
400
The total energy of motion and position of an object.
What is Mechanical Energy?
400
This energy is always a product of an energy conversion.
What is Thermal Energy?
400
A comparison of the amount of energy before a conversion with the amount of useful energy after a conversion.
What is Energy Efficiency?
400
A machine that turns water into electrical energy.
What is Turbine?
400

What is Gravitational Potential Energy?
500
A nuclear energy which involves the joining of four hydrogen nuclei to create a larger helium nucleus.
What is (Nuclear) Fusion?
500
Winding a rubber band on a toy airplane will give you this type of energy.
What is Elastic Potential Energy?
500
This, like a perfect machine, is impossible because of friction and the thermal energy that is wasted during energy conversions.

500
These three forms of fossil fuels are converted into other forms of energy.
What are Coal, Petroleum (Oil), and Natural Gas?
500
This energy is calculated by taking the mass of an object by its velocity squared, and then dividing it by 2.
