1. Potential and Kinetic Energy

2. How is all energy divided? Potential Energy Kinetic Energy All Energy Gravitation Potential Energy Elastic Potential Energy Chemical Potential Energy

3. What is Gravitational Potential Energy? oPotential energy due to an object ’ s position oP.E. = mass x height x gravity height x gravity

4. What is Elastic Potential Energy? oPotential energy due compression or expansion of an elastic object. Notice the ball compressing and expanding

5. What is Chemical Potential Energy? oPotential energy stored within the chemical bonds of an object

6. What is Kinetic Energy? oEnergy an object has due to its motion oK.E. =.5(mass x speed 2 )

7. What is Mechanical Energy? o Energy due to a object’s motion (kinetic) or position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!

8. What is Electromagnetic Energy? o Light energy o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

10. What is Thermal Energy? o Heat energy o The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement. A cooler object's molecules and atoms will show less movement.

11. What is Electrical Energy? o Energy caused by the movement of electrons o Easily transported through power lines and converted into other forms of energy

12. Law of Conservation of Energy Energy cannot be created or destroyed, only converted from one form to another.
