Energy exists in different forms
Energy can change forms but is never lost.
Technology improves ways energy is used.
Not a form of energy

What are the six forms of energy?
200
The energy conversion that occurs when a apple falls of a tree. Watch out Newton!
What is potential to kinetic?
200
This states that energy can not be created or destroyed.
What is the law of conservation of energy?
200
These convert sunlight into electricity.
What are solar cells(photo cell)?
200
The smallest part an element that retains its characteristics.
What is an atom?
200
Kinetic energy is determined by speed and this variable.
What is mass?
300
A box on a table has this because of its position.
What is potential energy?
300
This form of energy is released when the nuclei of some atoms are split.
What is nuclear energy?
300
The refrigerator that uses the greatest percentage of energy to cool or freeze food.
What is the refrigerator with the highest energy efficiency?
300
It is the absence of electromagnetic energy.
What is darkness?
300
When a generator spins it creates energy, but it is not 100% efficient because energy is lost in these forms.
What is heat and sound?
400
While the the football player carries the football down the field, these are the forms of energy he is using.
What are chemical, mechanical, kinetic, and potential?
400
The goal of this device is to convert nuclear energy to electricity.
What is a nuclear generator?
400
This is an advantage of LEDs.
What is almost all of the electricity they use is turned to light?
400
These make a compound.
What is a molecule?
400
After a coal-fired electric generating plant heats the water, the steam's kinetic energy is captured by the turbine to create this form of energy.
What is mechanical?
500
Five object/items or devices that emit electromagnetic energy.

500
Oyster Creeks Nuclear Power plants affect on Barnegat Bay, the water it uses in its operations.
What is it increases the thermal energy of the bay?
500
Energy from brakes is captured and charges a battery that drives an electric motor.
What is hybrid technology?
500
A large ball of matter that combines fuses hydrogen atoms and creates helium atoms. In this process it releases electromagnetic energy.
