Energy
What is the ability to do work?
100
energy conversion
What is a change from one form of energy to another form of energy?
100
This is a force that opposes motion between two surfaces that are touching.
What is friction?
100
This is a natural resource that can be converted by humans into other forms of energy in order to do useful work.
What is energy resource?
100
These energy resources can be used and replaced in nature over a relatively short period of time.
What are renewable resources?
200
Kinetic energy
What is the energy of motion?
200
At the top of your jump on a trampoline, this energy has been converted into potential energy.
What is kinetic energy?
200
On a roller coaster, this energy form is at its greatest at the top of the first hill.
What is potential energy?
200
These energy resources cannot be replaced after they are used or can only be replaced after millions of years.
What are nonrenewable resources?
200
By multipling weight X height
What is, finding the gravitational potential energy of an object?
300
Speed (velocity) and mass.
What determines Kinetic energy?
300
This energy is used in photosynthesis to convert carbon dioxide and water to sugar and oxygen.
What is light energy?
300
Due to this, not all of a roller coaster's potential energy can be converted into kinetic energy when rolling down a hill.
What is friction?
300
Coal, petroleum, and natural gas are the most common of these.
What are fossil fuels?
300
This energy resource is our most limitless resource and does not produce pollution.
What is solar?
400
Potential energy
What is energy an object has because of its position or shape.
400
In a light bulb, light energy and thermal energy has been converted from this energy form.
What is electrical energy?
400
Any time one form of energy is converted into another form, some of the original energy always gets converted into this.
What is thermal energy.
400
This energy uses radioactive material to boil water and produce steam to convert into electrical energy.
What is nuclear energy.
400
This energy resource produces thermal energy resulting from the heating of the Earth's crust.
What is geothermal energy.
500
Mechanical energy
What is the sum of all potential and kinetic energy or any amount of both.
500
These "things" are inventions of man that can both transfer and convert energy.
What are machines?
500
Energy can be neither created nor destroyed, according to this law.
What is the law of conservation of energy?
500
Organic matter such as plants, wood, and waste, that can be burned to release energy is called this.
What is biomass.
500
Energy is this ability to do work and work is the transfer of energy. Both energy and work are expressed by this measurement.
What are joules?
