**//Kinetic energy//** is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. //** Potential energy is converted into kinetic energy. **// Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy. A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy also happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States.

List five examples of **// potential energy //**. 1. A blown up balloon 2. A ball that has been picked up 3. A person standing still 4. Volcano about to erupt 5. A bike on the top of a hill

Nuclear energy is created two ways. the first one is to merge atoms together which realeases nuclear energy,This is how the sun creates energy. 


 * [[image:http://www.eia.doe.gov/energyexplained/images/fission.gif align="left" caption="Digraim of how fission splits the uranium atom."]] The second way to create energy is to separate atoms by cutting an atom in half which creates energy,This is called a**
 * fission,When this process happens it releases even smaller**
 * <--- particles called neutrons.**

The atoms are in groups of lots of atoms which create energy,this process is called fusion.

**All nuclear power in the United States ** Most U.S. uranium is mined in the Western United States.
 * is used to generate electricity! ** 

**Nuclear plants use a certain kind of uranium, as fuel because its atoms are easily split apart. Though uranium is quite common, about 100 times more common than silver, uranium is relatively rare.**  The sun realeases **HUGE** amounts of energy. -> 


 * Uranium is nonrenewable, though it is a common metal found in rocks all **
 * over the world! **

In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use this energy to produce electricity. When this process happens it releases even smaller particles called neutrons.

 Owners and operators of U.S. civilian nuclear power reactors purchased the equivalent of 53 million pounds of uranium during 2008. Uranium delivered to U.S. reactors in 2008 came from six continents:
 * Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. **
