1. 1 – WHAT IS ENERGY? 2 – FORMS OF ENERGY 3 – ENERGY TRANSFORMATION 4 – ENERGY TRANSFER

2.  INTERNATIONAL SYSTEM OF UNITS –  1 (joule) represents the energy needed to lift an object weighing 1 (newton) to a height of 1 (meter)  1 N = 100 g  1 M = 100 cm  1 J = 100g x 100cm  1J = 1N x 1M

9. Energy Transfer GOING FROM ONE SOURCE TO THE NEXT CHANGING FROM ONE SOURCE TO THE ANOTHER

10.  Changing energy from one form of energy to another form of energy  Ex. A Burning log – molecules of log transform into radiant energy (light) & thermal energy (heat)

11. Pg. 41 Textbook

12.  A movement of energy from one place to another while maintaining it’s form  Ex. Mechanical energy of a car’s motor is transferred to mechanical energy to the car’s tires to move the car.

13. Energy Transfer Pg. 41 Textbook

14. Energy Transformation & Energy Transfer

15.  HEAT –  The transfer of thermal energy from one place to another.  Heat will always travel from the hotter place towards the colder place
