JONNY NELSON: Energy. There are lots of different types and lots of different ways of storing it. Chemical energy in a sparkler, elastic potential energy that fires a toy into the air, and many, many ...

The Principle of Conservation of Energy states that energy can be changed from one form to another but the total amount of energy does not change. Energy is measured in joules (J) and 1 J is ...
