Energy
[ Back ] [ Potential ] [ Kinetic ]

    Energy is what enables an object to do work.  Energy, like work, is measured in joules.  Energy can be created  many different ways which include: the combustion of petroleum, coal, natural gas, and wood.  

    Energy can be converted into numerous things.  These things are used in several different ways.  One example of how energy is converted and how it is then used is in electricity.  Energy is transformed into electricity using solar radiation.  

    To fully understand energy, conservation of energy must also be understood.  The law of conservation of energy states that energy cannot be created or destroyed (it can be transformed from one form into another, but the total amount of energy never changes).  In every object there is a certain amount of energy that doesn't change, even though it might seem to.  What we see in objects is the amount of potential energy and the amount of kinetic energy changed.  Potential energy and kinetic energy make up an object's total amount of energy.  PE+KE=Total Energy.
