• The ability to do work and cause change

• The ability to generate electricity only

• A force that acts on objects

The law of conservation of energy states:

• Energy can not be created and not be destroyed

• Energy can be created, but not destroyed.

• Energy Can not be destroyed, but Energy can be created

• Energy is created and then destroyed
