9. Types of Energy Kinetic Energy Potential Energy Mechanical Energy
Heat energy
Chemical Energy
Electrical Energy
Gravitational Energy

10. Kinetic Energy is energy that is in motion
Kinetic Energy is energy that is in motion. Moving water and wind are good examples of kinetic energy. Electricity is also kinetic energy because even though you can't see it happen, electricity involves electrons moving in conductors.

11. Potential Energy is stored energy
Potential Energy is stored energy. Examples of potential energy are oil sitting in a barrel, or water in a lake in the mountains. This energy is referred to as potential energy, because if it were released, it would do a lot of work.

12. Mechanical Energy is the energy of motion that does the work
Mechanical Energy is the energy of motion that does the work. An example of mechanical energy is the wind as it turns a windmill.

13. Heat energy is energy that is pushed into motion by using heat
Heat energy is energy that is pushed into motion by using heat. An example is a fire in your fireplace.

14. Chemical Energy is energy caused by chemical reactions
Chemical Energy is energy caused by chemical reactions. A good example of chemical energy is food when it is cooked.

15. Electrical Energy is when electricity creates motion, light or heat
Electrical Energy is when electricity creates motion, light or heat. An example of electrical energy is the electric coils on your stove.

16. Gravitational Energy is motion that is caused by gravity
Gravitational Energy is motion that is caused by gravity. An example of gravitational energy is water flowing down a waterfall.

17. Energy can change from one form to another
Energy can change from one form to another. Be able to identify what changed.

18. Machine Requirements
Machine must demonstrate at least ONE of the following simple machines:
Pulley
Lever
Wedge
Wheel and Axle
Inclined Plane
Screw

19. Pulley

20. Pulley

21. Lever

22. Lever

23. Lever

24. Wedge
Ball drops on top of wedge, wedge pushes down (wedges in) between a fixed block and a movable block, movable block pushes a ball off, or itself falls off, of another edge.... or presses a button and throws a switch

25. Wedge

26. Wheel and Axle

27. Inclined Plane

28. Screw

29. Screw

30. Machine must demonstrate at least TWO of the following:
Wave (sound or mechanical)
Collision
Chemical reaction
Temperature change
Magnetism
Electricity
Change of motion (acceleration)
Light

31. Wave
Sound

32. Wave
Mechanical

33. Collision

34. Chemical Reaction

35. Temperature Change

36. Magnetism

37. Electricity

38. Change of Motion
Acceleration

39. Acceleration
-Acceleration- the rate at which velocity changes with time
-Velocity = speed in a given direction

40. Acceleration
a change in velocity means a change in direction or speed or both which is acceleration
-Acceleration is a Vector (magnitude and direction)

41. Light

42. Machine must demonstrate ALL of the following:
Potential Energy
Kinetic Energy
Inertia
Momentum
Speed

43. Potential Energy (PE)
-Potential Energy-stored energy that results from the position or shape of an object.
-PE has the potential to do work

44. Gravitational Potential Energy (GPE)
-Def: Potential energy related to an objects height
-Depends on weight and height in relation to reference point
-Calculate: GPE = Weight x Height

45. Elastic Potential Energy (EPE)
-Def: Potential energy of objects that can be stretched or compressed
-EX: Bow of an archer

46. Kinetic Energy (KE)
-Kinetic Energy-the energy an object has due to its motion
-The amount of KE is due to an objects mass and speed
-KE increases as mass increases or speed increases

47. Inertia Tendency of an object to resist a change in motion
The more mass an object has the more inertia it has

48. Inertia Newton’s First Law of Motion-
An object at rest will remain at rest and an object in motion will remain in motion at the same velocity unless acted on by an unbalanced force.

49. Momentum
Momentum-a characteristic of a moving object by multiplying the object’s mass and velocity

50. Speed -Speed is a type of rate
-Rates tell you the amount of something that occurs or changes in one unit of time.
-Speed-the distance an object travels per unit of time.

51. Speed -Speed is a type of rate
-Rates tell you the amount of something that occurs or changes in one unit of time.
-Speed-the distance an object travels per unit of time.

52. Transfer of Energy
Machine must transfer energy from start to finish, adding energy for the next machine. The amount of force that exits your machine must be MORE than what begins it.

53. Construction Requirements
Machine must be no larger than 60 cm x 60 cm x 60 cm. This will be small. Use small parts.
Machine must be able to complete the process more than once. Parts can be replaceable, but you shouldn’t have to rebuild it.

54. Construction Requirements
Use trash or recyclable items for your machine. However, you may need to purchase things like marbles, magnets or dominoes. Think creatively.
You may build prototypes at home, but be prepared to construct the final product in class. You will have several days of class time for construction.

55. Other Details
Your machine may begin by a force from your hand or from another machine. You may coordinate with another machine to align your entry and exit points.
You cannot touch the machine after it starts
