11. Chapter 15
ENERGY!

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

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

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

15. Examples of Kinetic Energy

16. 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 HEIGHT DOUBLE 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

17. Examples of Potential Energy… What kind?

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

19. What is Mechanical Energy?
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!

20. Examples of Mechanical Energy

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

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

23. What is Chemical Energy?
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.

24. Examples of Chemical Energy

25. What is Thermal Energy?
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.

26. ELECTROMAGNETIC ENERGY

MECHANICAL ENERGY

27. 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

28. QUIZ TIME!

36. 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

37. How was energy converted or conserved?

38. How was energy converted or conserved?

39. How was energy converted or conserved?

40. How was energy converted or conserved?

41. C = speed of light (3 x 108 m/s)
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)

42. 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!

43. 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.

44. 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.
