Scientists define energy as the ability to
What is cause a change in matter?
100
Energy that comes from the sun is called this.
What is solar energy?
100
The transfer of thermal energy between objects with different temperatures is called this.
What is heat?
100
Coal, natural gas, and oil are all examples of this.
What are nonrenewable resources?
100
Light moves like this.
What is in a straight line?
200
The energy of motion
What is kinetic energy?
200
Energy stored in fuel can be released by a chemical reaction such as burning. When it's not being used it, it is potential energy. It needs a chemical reaction to change it to kinetic energy. This energy is called.
What is chemical energy?
200
A burner, a pot, and water are a set of parts acting together as a whole object. This is called a
What is a system?
200
Any material that can be used to satisfy a need is called this.
What is a resource?
200
Materials that allow heat to travel through them easily like copper and most metals are called this.
What are conductors?
300
The energy an object has based on its condition or position.
What is potential energy?
300
This is the combination of all the potential and kinetic energy that something has.
What is mechanical energy?
300
The transfer of heat from a hotter object directly to a cooler object is called
What is conduction?
300
Using less of something to make it last longer is called this.
What is conservation?
300
When heat of light bounces off an object it's called this.
What is reflection?
400
When a roller coaster car is sitting at the top of the ride - waiting to roll down - it has this kind of energy.
What is potential energy?
400
This energy is in the form of vibrations that travel through matter.
What is sound energy?
400
As a gas or a liquid is heated, the heat causes it to move upward. This transfer of thermal energy through the movement of a gas or a liquid is called.
What is convection?
400
Wind, water, and sunlight are examples of this.
What is a renewable resource?
400
When baking a cake, you use an electric mixer. This is an example of what?
What is electrical energy being transformed into motion?
500
A car is rolling down a hill. This is what determines how much potential and kinetic energy it has.
What is how far down it has rolled?
500
Refrigerators, microwaves, and toasters are all examples of this kind of energy.
What is electrical energy?
500
Solar energy travels as light, x-ray, radio, and ultravioelt waves. It also travels as infrared waves that carry thermal energy from the sun and from heat sources like fires and toasters. The transfer of energy by waves that move through matter and space is called this.
What is radiation?
500
When coal, oil, and natural gas are burned, gases are released into the atmosphere. These gases are called this.
What is pollution?
500
When I want to listen to music, I plug in my radio. What type of energy transformation is happening when I do that?
What is electrical energy to sound energy?
