9. ENERGY! Chapter 15

10. Chapter 15.1 – Energy Forms • ENERGY is the ability to do WORK • WORK is the Transfer of Energy

11. TYPES OF ENERGY Kinetic and Potential: GPE & EPE

12. The energy of MOTION Greek “kinetos” means moving Depends upon the objectsMASS and SPEED DOUBLE the mass and you DOUBLE the kinetic energy DOUBLE the speed and youQUADRUPLE the kinetic energy What is Kinetic Energy? KE=1/2 mv2

13. Examples of Kinetic Energy

14. What is Potential Energy? Potential Energy is energy that is stored as a result of position or shape. • Gravitational Potential Energy (PE=mgh) Depends on MASS, HEIGHT and the acceleration of GRAVITY (9.8 m/s2 ) • DOUBLE the MASS or the HEIGHTDOUBLE the Gravitational Potential Energy • Elastic Potential Energy • Objects that can be stretched or compressed • When stored energy is released it is converted to Kinetic Energy • EPE can be stored in compressed objects like springs

15. Examples of Potential Energy… What kind?

16. TYPES OF ENERGY Mechanical, Electromagnetic, Electrical, Chemical, Thermal And Nuclear

17. Energy due to a object’s motion (kinetic) and position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins! What is Mechanical Energy?

18. Examples of Mechanical Energy

19. Light energy Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands What is ElectromagneticEnergy?

20. Energy caused by the movement of electrons Easily transported through power lines and converted into other forms of energy What is Electrical Energy?

21. Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck. What is Chemical Energy?

22. Examples of Chemical Energy

23. Heat energy The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement. What is Thermal Energy?

24. QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY

25. QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy? MECHANICAL ENERGY

26. QUIZ TIME! What energy transformation occurs when an electric lamp is turned on? ELECTRICAL ENERGY  ELECTROMAGNETIC ENERGY

27. What types of energy are shown below? Mechanical and Thermal Energy (Don’t forget friction)

28. What type of energy is shown below? Chemical Energy

29. What types of energy are shown below? Electrical, Mechanical and Electromagnetic Energy

30. What type of energy is shown below? Chemical Energy (yummy)

31. What type of energy is shown below? Thermal Energy

32. Draw a flow map showing the flow of energy transformations in a car from starting vehicle to driving. You should have 5 different types of energy.

33. Energy Transfer Sound (mechanical) Electrical Thermal Mechanical Electrical Chemical Electrical Light (Electromagnetic)

34. Chapter 15.2 – Energy Conversion and Conservation • The law of conservation of energy states that energy cannot be created or destroyed However… • Energy can be converted from one form to another – and in either direction! • The gravitational potential energy of an object is converted into the kinetic energy of motion as the object falls • The BEGINNING TOTAL of KE + PE EQUALS the ENDING TOTAL of KE + PE

35. How was energy converted or conserved?

36. How was energy converted or conserved?

37. How was energy converted or conserved?

38. How was energy converted or conserved?

39. Energy and Mass E=MC2 • Einstein’s equation shows that ENERGY and MASS are equivalent and can be converted into each other • E=energy • M = mass • C = speed of light (3 x 108 m/s)

40. Energy and Mass E=MC2 • In other words, Energy is released as matter is destroyed and Matter can be created from Energy • Because the square of the speed of light is a very large figure: even a small chunk of matter can produce a large amount of energy!

41. Your Turn… • Think of an example from everyday life where potential energy is transformed into kinetic energy, or vice versa. • Draw a diagram that illustrates the transformation, using the interactive activity as an example. Then describe the transformation.

42. For example: When I carry a sled to the top of a snowy hill, the potential energy of the sled increases. As I stand with my sled at the top of the hill, the kinetic energy is zero and the potential energy is at its maximum. As I slide down the hill, the potential energy of the sled decreases and its kinetic energy increases.
