 SUBJECT: Energy |
 When you turn on the television, tie your shoelace or drive to the store, you're using energy. Energy is one of the most fundamental forces in the world. Animals use energy to walk and run. Trees and plants use energy to grow. People use it to work and play.
Energy is everywhere in nature - in the light of the sun, in the wind, in the forest, in falling water and erupting volcanoes. Without energy, there is no life. We use our own energy constantly - and we continually make use of all kinds of energy.  Energy makes everything happen and can be divided into two different types. Stored energy is called potential energy. Energy in motion is called kinetic energy. If you have a rubber band, stretch it out. The stretched rubber band has potential energy. If you let it go, it moves and has kinetic energy. |
