This natural law states that the total amount of energy in a system always stays the same.
What is the Law of Conservation of Energy?
100
The kinetic energy of particles that occurs when vibrations pass to surrounding air particles and then from one air particle to another in a wave of energy is known as this.
What is sound energy?
100
These are negatively charged subatomic particles that make up electricity.
What are electrons?
100
The total kinetic energy of all the atoms that make up an object is known as this.
What is thermal energy?
100
This is the unit for energy.

200
Mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms are known as this.
What is a fossil fuel?
200
Burning fossil fuels release this into the atmosphere.
What are greenhouse gases?
200
Wind, solar, geothermal, hydroelectric, and biomass are examples of this type of resources.

What are nonrenewable resources?
400
The problem with nuclear fission is this.
What is the production of long-term radioactive waste?
400
Energy released by stars into space that travel space as electrical and magnetic waves are nown as this.

400
Natural resources that can be replaced in a relatively short period of time or are virtually limitless in supply are known as this.
What are renewable resources?
500
This type of energy accounts for both the kinetic and potential energy of an object.
What is mechanical energy?
500
A type of nuclear reaction where atoms are slammed together to create heavier atoms and release energy is known as this.
What is a fusion reaction?
500
The energy stored in the bonds between atoms that make up compounds is known as this.
What is chemical energy?
500
This is the type of energy derived from the nuclei of atoms.
