1. ENERGY! And Energy Transmission

2. Lets first review Work  Work = Force (N) x Distance  In every simple machine that we have seen, when someone does work on the machine, the machine does work on a load  Work is a transfer of ENERGY

3. ENERGY  Is the ability to do WORK  It can be neither created nor destroyed  There are different types and forms

4. Forms of Energy  Kinetic  Potential  Chemical  Gravitational

5. Kinetic Energy The Energy of Motion

6. Potential Energy = Stored Energy  Chemical Potential Energy  Your body  Energy for Machines  Gravitational Potential Energy  Lifting an object higher increases the gravitational potential energy

7. Potential Energy

8. Other Types of Energy  Other types  Chemical  Electrical  Mechanical  Sound  Electrochemical (battery)  Electromagnetic (light)  Nuclear

9. Other Types of Energy  Green  Hydropower  Biomass  Geothermal  Solar  Wind

10. Energy Transmission  Energy (or power) can be transmitted/transfo rmed  The energy is transferred from one place to another, and no energy is changed or converted
