1. Transfer of Energy

2. Forms of Energy Potential ChemicalMechanical Kinetic Thermal Radiant Electromagnetic (8 th ) Nuclear (8 th )

3. Thermal/Heat Energy Motion of Atoms Measured by change in Temperature We produce heat energy.

4. Chemical Energy Chemical Energy is required to bond atoms together. And when bonds are broken, energy is released

5. Mechanical Energy When work is done to an object, it acquires energy. The energy it acquires is known as mechanical energy. Mechanical energy is motion.

6. Radiant Energy Energy that comes from the Sun.

7. Now we will discuss: Energy Transformations and how it allows us to do work Transform – It might change shape or form, but it still contains all the same things!!

8. How we transform ENERGY! Cells HeatMechanical Stomach Macromolecules Chemical Energy Food

9. Energy Transformation Heat Mechanical Chemical

10. Transfer of Energy For example, heat and the small molecules of water are the by-products of metabolism. Chemical Energy  Mechanical & Heat Energy Heat co 2 H2OH2O +

11. What type of Energy is being transformed?

12. THE MOST IMPORTANT TYPE OF ENERGY TRANSFORMATION WHAT IS THE ULTIMATE AND MOST IMPORTANT SOURCE OF ENERGY???

13. Where does almost ALL energy come from? The Sun
