This is an example of the suns energy being changed to chemical energy.
What is photosynthesis or leaves turning green?
100
When two atoms are forced together.
What is fusion?
100
This type of energy is produced by the vibrations of matter. These vibrations can move through solid, liquid or gaseous matter, but they cannot travel through empty space.
What is sound energy?
200
A force (a push or pull) applied to an object which forces the object to move.
What is work?
200
Energy an object has due to its motion, position or condition.
What is mechanical energy?
200
This is an example of the suns energy being changed to electrical energy.
What is a solar powered calculator?
200
When an atom is broken apart.
What is fission?
200
This is what you feel when you put your hand on the speaker of a radio that is turned on.
What are vibrations?
300
The energy any object has because of its motion.
What is kinetic energy?
300
Energy formed when an atom splits apart or when two atoms join to form one.
What is nuclear energy?
300
This is an example of electrical energy being changed to light energy.
What is a lamp?
300
An example of something that uses fission is this.
What is the sun?
300
