Task 1) Identify the different types of Energy
The Conservation of Energy Law
Energy cannot be created or destroyed. It can only be transformed from one type into another
or transferred from one object to another.
Energy Transformation Diagrams
• An energy transformation diagram shows how energy is transformed from one kind to another.
Example: the operation of a television.
