  1. SCREW LEVER SIMPLE MACHINESMAKING WORK EASIER! PULLEY INCLINED PLANE WHEEL AND AXLE WEDGE

  2. SIMPLE MACHINES ARE DEVICES THAT HELP US DO WORK SIMPLE MACHINES DO NOT HAVE ENERGY SOURCES OF THEIR OWN SIMPLE MACHINES DO NOT DO ANY WORK BY THEMSELVES SIMPLE MACHINES SIMPLY TRANSFER WORK DONE BY A HUMAN TO SOMETHING ELSE SIMPLE MACHINES

  3. SIMPLE MACHINES CAN CHANGE THE AMOUNT OF FORCE REQUIRED TO DO WORK. SIMPLE MACHINES CAN CHAGES THE DISTANCE THROUGH WHICH THE FORCE ACTS OR THE DIRECTION IN WHICH IT ACTS. SIMPLE MACHINES ALLOW HUMANS TO DO THINGS THAT THEY OTHERWISE MIGHT NOT BE ABLE TO DO. ADVANTAGES OF USING SIMPLE MACHINES

  4. THE WEDGE IS A MOVING INCLINED PLANE THE WEDGE INCLINED PLANE AT REST INCLINED PLANE USED AS A WEDGE CHOPING WOOD IS AN EXAMPLE OF USING AN INCLINED PLANE AS A WEDGE

  5. THE SCREW IS AN INCLINED PLANEWRAPPED AROUND A SHAFT THE SCREW SCREWS MAKE WORK MUCH EASIER! SHAFT SCREWS WITHOUT AN INCLINED PLANEWRAPPED AROUND ASHAFT, WE WOULD NOT BE ABLE TO EASILY FORCE A SHAFT INTO MATERIALS LIKE WOOD OR METAL.

  6. THE WHEEL AND AXLE IS AN OFTEN MISUNDERSTOOD SIMPLE MACHINE IT IS BASICALLY A LEVER THAT CAN MOVE IN A CIRCLE THE WHEEL AND AXLE THE WHEEL MUST BE ATTACHED TO THE SHAFT(AXLE) TO TRANSFER FORCE TO IT! THE STEERING WHEEL IN A CAR AND THE SHAFT IT IS ATTACHED TO IS AN EXAMPLE OF A WHEEL AND AXLE WHEEL AND AXLE

  7. A LEVER IS A BAR THAT CAN REST ON AND TURN AROUND A SUPPORT CALED A FULCRUM. THE FORCE YOU APPLY TO ONE PART OF THE LEVER IS CALLED THE EFFORT THE WEIGHT THAT IS LIFTED OR THE RESISTANCE THAT IS OVERCOME IS CALLED THE LOAD. THE LEVER LEVER EFFORT LOAD FULCRUM

  8. THE PULLEY IS A GROOVED WHEEL WITH A ROPE OR CABLE AROUND IT PULLEYS HELP US DO WORK BY MOVING OBJECTS UP, DOWN, OR ACROSS. THE PULLEY EFFORT LOAD WHEN THE EFFORT IS PULLED IN ONE DIRECTION THE LOAD GOES IN THE OTHER DIRECTION SINGLE PULLY PULLEY ON A SHIP GROOVED WHEELS

  9. THE INCLINED PLANE IS A SLANTING SURFACE CONNECTING A LOWER LEVEL TO A HIGHER LEVEL THE INCLINED PLANE THE SLIDE IS A MODIFIED INCLINED PLANE COMMERCIAL RAMP FOR MOVING HEAVY BOXES INTO A TRUCK

  10. THE REMAINING SLIDES ARE A QUIZ ENJOY!
