Electrical potential energy
Magnetic potential energy

3. Gravitational Potential Energy
The amount of energy stored in an object that is above a reference point

4. Gravitational Potential Energy
Depends on
The height of an object above a reference point
The mass of the object
Gravity (9.81 m/s2)
Eg = mgh

5. Elastic Potential Energy
The amount of energy stored in an object that is being stretched or compressed from its resting position

6. Elastic Potential Energy
Depends on
The distance from the resting point (Δx= distance)
Δ means change
The resistance of the object to stretch or compress (k= spring constant)
Eelastic = ½ k (Δx)2

7. Chemical Potential Energy
Potential energy stored in the position and arrangement of atoms

8. Chemical Potential Energy
Depends on the rearrangement of atoms that make up the new substance
(Chemical reaction)

9. Endothermic Reaction that require energy
LIGHT ENERGY CONVERTS TO CHEMICAL ENERGY

10. Endothermic
Examples
Food to Energy

11. Exothermic
Reaction that
releases
energy

12. Exothermic
Example

13. Electrical Potential Energy
Energy stored in the position of electrically charged particles

14. Electrical Potential Energy
The position of the charged particles
The change in the position of the charged particle

15. Magnetic Potential Energy
Energy stored in magnetic objects

16. Magnetic Potential Energy
The position of the magnetic objects relative to each other
