Energy transfer

CONSERVATION OF ENERGY PRINCIPLE

There are many different types of energy but they all follow this same principle:

ENERGY CAN BE TRANSFERRED USEFULLY FROM ONE FROM TO ANOTHER, STORED OR DISSIPATED - BUT IT CAN NEVER BE CREATED OR DESTROYED! NEVER. 

Disipated - fancy way of saying the energy is spread out AND lost. 

ENERGY IS ONLY USEFUL WHEN IT CAN BE CONVERTED FROM ONE FORM TO ANOTHER. 

DONT FORGET THIS!
