1. Energy Forms and Transformations Objective: Examine the various forms of energy in order to identify and describe specific energy transformations.

2. DIRECTIONS: Use the information contained on the following slides to complete your “Energy Concept Web”. Advance to the next slide by clicking your mouse or by pressing the “down arrow” key one time.

3. Energy the “stuff” that makes “stuff do stuff” OR the ability to do work. (W=F x D) (F=force d=distance)

4. Types (kinds) of Energy KE (kinetic energy) PE (potential energy)

5. Forms of energy Mechanical Heat/Thermal Chemical Electrical Electromagnetic Nuclear

6. Mechanical Energy Energy of motion or position Sound, wind, waterfall, compressed spring KE or PE Not 100% efficient much lost to heat

7. Heat/Thermal Energy The internal motion of an objects atoms and molecules. Measured by temperature. The faster particles move, the more thermal energy they have. KE only

8. Chemical Energy Energy stored by chemical bonds in an object. When bonds are broken energy is released. PE only gasoline, food, coal, wood

9. Electrical Energy Moving electrical charges. Electricity from batteries, power lines, lightning KE

10. Radiant Energy energy that travels in waves; have electrical and magnetic properties Light, Magnetism, X- Rays, Radio waves, microwaves, ultraviolent and infrared radiation KE

11. Nuclear Energy Energy stored in center(nucleus) of an atom Fission (breaking apart) Fusion (forming) The sun Most powerful PE only
