9 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Workshop 2

10 14.-19. April 2013Mallinckrodt-Gymnasium Dortmund Workshop 2 Emphasis on Energy in science Mobility in the 21. century

11 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund What is energy? Energy is the ability to work.

12 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund What is work? Everyday language: Expenditure of muscular effort Science: an applied force moves an object through a distance.

13 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund What is work? Examples Lifting work Accelerating work Frictional work Streching work

14 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Work W is done, when a force F moves a body a distance d in the direction of the movement. W = F · d [ W ] = Nm = J (Joule)

15 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Lifting work Lifting Work stored as potential energy Accelerating work Potential energy transformed to kinetic energy kinetic energy transformed to potential energy Accelerating work stored as kinetic energy

16 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Workshop 2 Work ist stored as Energy. Lifting Work potential Energy Accelarating Work kinetic Energy Frictional Work Heat Energy

17 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Three principles of energy Energy can be transfered from one body to another. 1) Transfer of energy

18 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Three principles of energy Any form of energy can be transformed into another form. 2) Transformation of energy

19 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Three principles of energy Energy can not be destroyed or created. 3) Conservation of energy

20 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund 3) Conservation of energy Potential energy Kinetic energy Thermal energy Light energy } lost

21 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Forms of energy Thermal energy Mechanical energy Thermal (Heat) energy Light energy Electric energy Magnetic energy Nuclear energy Chemical energy Energy of sound

22 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Cruachan Power Station Energy balance Electric energy Potential energy Kinetic energy Electric energy thermal energy (friction) Energy chain Ecologically usefull?

23 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Niagara falls power station Electric energy Kinetic energy of water Potential energy of water ???

24 Workshop 214.-19. April 2013Mallinckrodt-Gymnasium Dortmund Energy: The most important concept of physics Energy: One of the most imortant subjects in everyday life.
