The energy of motion
What is kinetic energy?
100
The ability to do work (SON).
What is energy?
100
The change of one form of energy into another.
What is energy conversion?
100
This force opposes motion and is often the "lost" energy in energy conversion.
What is friction?
100
This is a natural resource that can be converted by humans into other forms of energy.
What is energy resource?
200
Energy an object has due to its position and shape.
What is potential energy?
200
The Energy that depends on an objects height and weight.
What is gravitational potential energy?
200
Jumping on a trampoline and a swinging pendulum are examples involving conversions of what two main energy types?
What are kinetic and potential?
200
A well defined group of objects that transfer energy between one another.
What is a closed system?
200
These cannot be replaced or take several thousands or millions of years replaced.
What are nonrenewable resources?
300
The sum of an object's kinetic and potential energy.
What is mechanical energy?
300
The total energy of the particles that make up an object.
What is thermal energy?
300
Photosynthesis converts what type of energy into what type of energy?
What is light into chemical?
300
This states that energy can be neither created nor destroyed.
What is the law of conservation of energy?
300
These are energy resources that formed from the buried remains of plants and animals that lived millions of years ago.
What are fossil fuels?
400
The energy of a compound that changes as its atoms are rearranged to form new compounds.
What is chemical energy?
400
Energy caused by an object's vibration.
What is sound energy?
400
Give three examples involving conversions of electrical energy.
What is alarm clock, battery, light bulb, blender, hair dryer, etc?
400
Friction results in this type of energy that is lost in energy conversions.
What is thermal energy?
400
These are the three main types of fossil fuels.
What are coal, petroleum, and natural gas?
500
Energy caused by the vibration of electrically charged particles.
What is light energy?
500
Energy associated with changes in the nucleus of an atom.
What is nuclear energy?
500
Energy efficiency compares these two things.
What is energy before a conversion with energy after the conversion?
500
This type of motion would be perfect, resulting in a machine that runs forever with no additional energy.
What is perpetual motion?
500
These are the the FIVE most common RENEWABLE energy resources.
What are solar, water, wind, geothermal, biomass?
