Simple machines

  1. 1. SIMPLE MACHINES By: Clarisse Mallari Chermaine de los Reyes Next
  2. 2. At the end of the lesson, the class will be able to identify the different simple machines. Back Next
  3. 3. Simple Machines Considered to be building blocks of machines It helps the people make their work easier The 1st machines are often called “the 6 simple machines” LET'S FIND OUT WHAT THESE MACHINES ARE! :-) Back Next
  4. 4. The 6 SIMPLE MACHINES: click the machine you want to know :-) Lever Wheel & Axle Screw Inclined Plane Pulley Wedge Back Next
  5. 5. Lever Resistance force / load Effort force constructed from a beam attached to ground by a hinge, or fulcrum The fulcrum balances 2 forces: an effort force and a resistance force, or load Hinge/ Back Next Fulcrum
  6. 6. These are some other examples of Lever machines :-) Back HOME Next
  7. 7. Wheel And Axle A wheel with a rod, called an axle, through its center lifts or moves loads. They're everywhere! A large circle (wheel) connected to a smaller circle (axle) links distance traveled and power needed in an incredibly useful way Back Next
  8. 8. These are some other examples of Wheel and Axle machines :-) Back HOME Next
  9. 9. Inclined Plane A slanting surface connecting a lower level to a higher level. Back Next
  10. 10. These are some other examples of Inclined Plane :-) Back HOME Next
  11. 11. Pulley A simple machine that uses grooved wheels and a rope to raise, lower or move a load. Each section of string supporting the movable pulley system decreases the force needed to move the load Back Next
  12. 12. These are some other examples of Pulley machines :-) Back HOME Next
  13. 13. Wedge An object with at least one slanting side ending in a sharp edge, which cuts material apart. Back Next
  14. 14. These are some other examples of Wedge:-) Back HOME Next
  15. 15. Screw An inclined plane wrapped around a pole which holds things together or lifts materials. Back Next
  16. 16. These are some other examples of Screw :-) Back HOME EXERCISE! :)
  17. 17. Now, are you familiar with the simple machines you've seen? Let's test how you remember them. We will have some few exercises! Click the “Start” button if you are ready. Let's go! :-) Start Back
  18. 18. What am I? You can usually find me during flag ceremonies, I help the flag reach the top of the pole. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  19. 19. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  20. 20. CORRECT! :) I am a pulley and you can usually find me on top of the flag pole. It is easier for me to pull down and push up because of the movable rope that supports me :-) Back Next question
  21. 21. What am I? I help Mr. Porter put the box to the truck. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  22. 22. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  23. 23. CORRECT! :) I am a inclined plane and you can always use me as a guide to transfer heavy things inside a truck Back Next question
  24. 24. What am I? Hey-o-hey-o, said the dwarf as he lift me to whack that rock into two. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  25. 25. CORRECT! :) I am a wedge and you can always use me to cut materials apart because I usually have slanting side ending in a sharp edge :-) Back Next question
  26. 26. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  27. 27. What am I? I am Mr. See-saw. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  28. 28. CORRECT! :) I am a lever and I can be a seesaw for you and your playmate :-) Back Next question
  29. 29. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  30. 30. What am I? “I need you,” said Mr. Hinge, “the Door and I can't connect.” Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  31. 31. CORRECT! :) I am a hinge. A hinge is a kind of screw that you can see between the side of the door and the wall attaching it. It is the one that makes the door open properly :-) Like this: Back Next question
  32. 32. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  33. 33. What am I? The cyclist is looking for me, his bike won't move without me. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  34. 34. CORRECT! :) I am a wheel and an axle. A bike is an excellent example of it, because of the wheel that makes it to move and a screw to secure it :-) Back Next question
  35. 35. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  36. 36. What am I? “Cut-cut-cut” said the scissors. I will cut your paper into half Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
  37. 37. CORRECT! :) I am a wedge and you can always use me to cut materials apart because I usually have slanting side ending in a sharp edge :-) Back Next question
  38. 38. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  39. 39. What am I? “Wiii”, said the child as she slide on me. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back
  40. 40. WELL DONE! :) I am an inclined plane and sometimes I can also be a slide in playgrounds and fun parks :-) Next Back
  41. 41. OOPS! THAT'S NOT ME. YOU CAN TRY AGAIN Try Again
  42. 42. CONGRATULATIONS! You have successfully identified the different kinds of simple machines. You might think of it as “simple” yet it has many uses, and those are the special meanings in physics. When a force moves an object, that is what we now call “work” :-) Next
  43. 43. I hope you have learned enough information about our topic today. Always remember, examples of these things are not simple machines: Next
  44. 44. This is not a simple machine. This is WALL-E. A complex robot machine. Next
  45. 45. Neither is Bumblebee from transformers. This is really a complex- transforming robot. Next
  46. 46. Well yes. Washing machine makes your life easier, BUT this is not identified as simple machine! It has complex functions in it Next
  47. 47. Especially this! This is a machine. But this is machine gun, not for simple purposes. You know what I mean. Next
  48. 48. BUT this. We are not machines, we are just SIMPLE :-) THANK YOU FOR TRYING OUR LEARNING OBJECT! HOPE YOU HAD FUN! :-) This work is licensed under a Creative Commons Attribution 3.0 Unported License.
