2. Forms of Energy andEnergy Conservation

3. Does the energy stay in one form?

4. Energy conversion • Energy cannot be made • Energy cannot be destroyed or “used up” • Energy can just change from one form to another. • Kinetic -> Potential -> Kinetic

5. Law of Conservation of Energy • Energy cannot be created or destroyed, only changed in form.

6. Seven forms of energy • Energy is the ability to make things do work • Energy has no mass and no volume • Energy can be found in 7 different forms

7. Mechanical Energy • Energy due to the position or motion of an object

8. Sound Energy • Energy of vibrating air molecules

9. Chemical Energy • The energy used to hold atoms in a molecule together, such as in food or fuel. • Chemical bonds are broken during a chemical reaction (burning, rusting, digestion)

10. Electrical Energy • The movement of electrons through matter. • Electricity is a form of electrical energy.

11. Light Energy • Energy carried by light, x-rays, microwaves

12. Electromagnetic Energy • Visible light is a form of electromagnetic energy. • Each color of light (Roy G Biv) represents a different amount of electromagnetic energy.

13. Thermal (heat) Energy • The vibration of particles of matter. • More vibrations = more heat energy (hotter) • Fewer vibrations = less heat energy (cooler)

14. Nuclear Energy • The energy that holds protons and neutrons together in the nucleus of an atom
