1. Forms of Energy

2.  Forms of energy related to changes in matter are kinetic, potential, chemical, electromagnetic, electrical, and thermal

3.  Kinetic energy is the energy of matter in motion  Potential energy is the energy an object has because of its position

4.  (EG) A rolling bowling ball has KE and can do work by knocking down pins.

5.  (EG) when a diver climbs up a diving board, he/ she increases her PE

6.  Is energy stored in a chemical bond EG: Methane

7.  It is released when the bond is broken and new bonds are formed

8.  It is a form of potential energy

9.  When a chemical change occurs bonds are broken and new bonds are formed, if it’s exothermic some of the chemical energy is transformed and released in other energy forms

10.  Electromagnetic is a form of energy that travels through space in the form of waves. 

11.  Can also cause physical changes

12.  (EG) Radio, infrared, light, x-rays, microwaves

13.  (EG) the microwave can change a frozen block of spaghetti into a hot meal, this is a physical change

14.  Electrical is the energy of electrically charged particles moving from one place to another

15.  Electrodes are metal strips that conduct electricity

16.  Electrolysis: Is a chemical change that involves electricity. Two metal strips are placed in a solution but do not touch. Each electrode is connected to a battery. When the energy begins to flow, atoms of one kind lose electrons at one electrode in the solution. At the other electrode, atoms of a different kind gain electrons, and a new substance results. 

17.  During a chemical change chemical energy may be changed to other forms of energy. Other forms of energy may also be changed to chemical energy

18.  (EG) Photosynthesis: Electromagnetic energy to chemical energy

19.  (EG) Burning a fuel: Chemical to electromagnetic and thermal
