1. Sun Source of almost all the energy is the… Wood, coal, petroleum and natural gas come from the sun. The USA gets 90% of its energy from fossil fuel.

2.  Can take the shape of many different forms.  Two Categories: Kinetic or Potential  Kinetic Energy is energy of motion– of waves, electrons, atoms, molecules, substances and objects  Potential Energy is stored energy and the energy of position– gravitational energy. There are several forms of potential energy Energy is the ability to do work

4.  stored energy  Burning is a chemical change  Our bodies use food and give off energy in the form of body heat.  An adult radiates heat energy equal to 100 W light bulb.  All the energy that is transferred through living organisms. Types of Potential Energy

5.  Stored in objects by tension  Compressed springs and stretched rubber bands are examples of stored mechanical energy.  Sometimes known as elastic energy. Mechanical Energy (potential)

6.  - stored in an atom’s nucleus  Fusion- the combining of nuclei  Ex. The sun or any star  Fission- the splitting of a nucleus  Like in the bombs or nuclear reactors Nuclear Energy (potential)

7.  Energy stored in an object’s height.  The higher and heavier the object, the more gravitational energy is stored.  When you ride a bicycle down a steep hill and pick up speed, gravitational energy is being converted to motion energy. Gravitational Energy (Potential)

8.  - electromagnetic light waves Light Energy (Radiant)

9.  how fast matter is moving  movement of thermal energy is heat  Measured by temperature  Temperature is a measure of how much thermal energy (or heat) is in matter Thermal Energy

10. Motion Energy  energy stored in the movement of objects.  The faster they move, the more energy is stored.  It takes energy to get an object moving, and energy is released when an object slows down.  Wind is an example of motion energy. Types of Kinetic Energy

11.  - vibrational energy  The loudness depends on how much energy the sound wave has. Sound Energy

12.  Static electricity- is a build up of electrons  Current electricity is the movement or flow of electrons Electric Energy

13.  Energy cannot be created or destroyed. It is transformed or transferred.  Energy can be changed (or transferred) from one form into another.  http://www.youtube.com/watch?v=k60jGJfV8oU&feature=plcp http://www.youtube.com/watch?v=k60jGJfV8oU&feature=plcp The Law of Conservation of Energy states...
