What is Energy ? The ability to do work or cause change. Energy can NEVER be created or destroyed it can only change forms. This is referred to as Law.
 Potential energy can transform into kinetic energy or kinetic energy can transform into potential energy. Ex: When a rubber band is stretched, kinetic.
 Energy is the ability to cause change.  Anytime change occurs, energy is transferred from one object to another.  Energy can be in many different.

SOLAR ENERGY MODULE D

ENERGY The ability to do work or change matter

WORK The movement of an object

FORMS OF ENERGY Sunlight Heat Sound Electricity

JOULES A unit of measurement for energy and work

POWER The rate at which work is done

WATT A unit of measurement for power You can see this written on a light bulb The higher the number, the more power

CHANGING ENERGY Potential Energy Kinetic Energy

POTENTIAL ENERGY Stored energy Energy without motion

KINETIC ENERGY Energy in motion

EXAMPLES Toy duck Rubber band Swing Sled Rollercoaster
