Energy

=Energy=

Energy under normal conditions cannot be created or destroyed, simply transformed from one type of energy to another. Scientists say energy is the ability to do work such as moving something or changing it's temperature. Energy is measured in Joules (J). The different forms of energy are named for the way they are produced or because of some characteristics they have: A book on a shelf has **gravitational potential energy**, while a car speeding along a road has **kinetic energy**. A nuclear reactor produces **nuclear energy**. A lamp burning gives of light (**radiant energy**) and heat (**thermal energy**). A generator produces **electrical energy**. An ambulance siren gives out **sound energy**, while it's battery contains **chemical potential energy**. Finally a stretched rubber band contains **elastic potential energy**.
