THE STUDY OF THE PROPERTIES OF MATTER AND ENERGY IS CALLED _______?: PHYSICS
TO DETERMINE THE IDEAL MECHANICAL ADVANTAGE FOR AN INCLINED PLANE (FORMULA): IDEAL MECH. LENGTH OF BOARD
ADV. = _______________
HEIGHT OF THE
INCLINE
(DIVIDE LENGTH X HEIGHT)
MECHANICAL ADVANTAGE = (FORMULA): MECHANICAL ADVANTAGE =

OUTPUT FORCE
____________
INPUT FORCE
THERE ARE ___ CLASSES OF LEVERS?: 3
WHAT IS FORCE?: A PUSH OR PULL
A LONGER INCLINED PLANE AT THE SAME HEIGHT GIVES THE WORKER A _____ MECHANICAL ADVANTAGE. (GREATER, LESS): GREATER
THE FORCE EXERTED ON A LOAD BY A MACHINE IS CALLED?: OUTPUT FORCE
IN A MOVEABLE PULLEY, THE WHEEL IS ATTACHED TO WHAT?: THE WHEEL IS ATTACHED TO THE LOAD. THE WHEEL MOVES UP AND DOWN WITH THE LOAD
HOW IS FRICTION HELPFUL?: ALLOWS US TO SLOW DOWN A CAR, GRAB AN OBJECT, STOP WHEN WE ARE RUNNING
DESCRIBE A WEDGE: IT HAS A THICK END THAT TAPERS INTO A THIN, POINTED END
TOOLS MAKE WORK EASIER BECAUSE?: THEY CHANGE THE FORCE APPLIED TO THE WORK
CLASS ONE LEVERS CONSIST OF:: -A ROD
-FULCRUM
-LOAD ARM
-EFFORT ARM
FRICTION MAKES WORK MORE __________: DIFFICULT - BECAUSE OF FRICTION WE NEED TO INCREASE FORCE FOR WORK TO TAKE PLACE
WHAT SIMPLE TOOL SPREADS OUT FORCE OVER A LONGER DISTANCE?: INCLINED PLANE
ANYTHING THAT USES TWO OR MORE SIMPLE TOOLS IS CALLED?: A COMPLEX MACHINE
EXAMPLES OF A WHEEL AND AXLE INCLUDE:: -STEERING WHEEL
-A WATER WHEEL
-DOORKNOB
THE AMOUNT OF FRICTION DEPENDS UPON WHAT?: THE AMOUNT OF FORCE BETWEEN THE TWO OBJECTS OR SURFACES. THEREFORE, HEAVIER OBJECTS CREATE MORE FRICTION WHEN BEING MOVED.
AN INCLINED PLANE HAS A _____ SURFACE USED TO _____ A LOAD: SLANTED

RAISE
THE SIX BASIC TOOLS ARE:: INCLINED PLANE, WEDGE, SCREW, LEVER, WHEEL AND AXLE, AND PULLEY
IN A CLASS ONE LEVER, THE FULCRUM IN LOCATED WHERE?: BETWEEN THE LOAD AND EFFORT, DIVIDING THE LEVER (BAR) INTO TWO SIDES
WORK IS INCREASED IN TWO WAYS: -AN INCREASE IN THE WEIGHT OF THE LOAD
-AN INCREASE IN THE DISTANCE MOVED
THE FORCE USED TO PUSH A LOAD ON AN INCLINED PLANE IS CALLED:: THE INPUT FORCE
TOOLS DO WHAT TO FORCE?: -MAGNIFY FORCE
-ALTER THE DIRECTION OF THE FORCE
A FIXED PULLEY CHANGES THE DIRECTION OF WHAT?: THE INPUT FORCE
WORK IS DEFINED AS (FORMULA): FORCE X DISTANCE = WORK
IN A CLASS ONE LEVER THE SIDE THAT HOLDS A LOAD IS CALLED?: THE LOAD ARM
FRICTION CAN BE DECREASED IN TWO WAYS: -LUBRICATION
-WHEELS
WHERE IS THE FORCE APPLIED TO A CLASS THREE LEVER?: BETWEEN THE FULCRUM AND THE LOAD
FRICTION IS GREATEST WHEN?: JUST BEFORE AN OBJECT MOVES
IN A CLASS ONE LEVER, THE SIDE THAT FORCE IS APPLIED TO IS CALLED?: THE EFFORT ARM
IN ORDER FOR WORK TO TAKE PLACE _____________________: A FORCE MUST ACT ON A LOAD AND MOVE IT
TRUE/FALSE A FIXED PULLEY CAN HAVE MORE THAN ONE WHEEL IN THE SYSTEM: TRUE
WHAT IS A LOAD?: THE OBJECT TO BE MOVED
LIST SOME EXAMPLES OF A WEDGE: -PLOW
-ZIPPER
-SCISSORS
-AX
-DOOR STOP
STARTING FRICTION HAS: 1. MOST FRICTION 2. LESS FRICTION 3. LEAST FRICTION: 1. MOST FRICTION (GREATEST AMOUNT OF FRICTION)
WHEEL AND AZLE - WHEN THE WHEEL TURNS, DOES THE AXLE TURN OR STAND STILL?: THE AXLE TURNS
SLIDING FRICTION HAS: 1. MOST FRICTION 2. LESS FRICTION 3. LEAST FRICTION: 2. LESS FRICTION
HOW DOES FORCE EFFECT A WEDGE?: WHEN FORCE IS APPLIED TO THE THICK END OF THE WEDGE, THE POINTED END WILL GO UNDER OR INTO AN OBJECT
IN A CLASS ONE LEVER, IN WHAT DIRECTION DO THE LOAD AND EFFORT MOVE? (SAME OR OPPOSITE DIRECTION): OPPOSITE
EXAMPLES OF SCREWS:: -FAUCET
-DRILL
-VICE
-NUTS/BOLTS
IN THE SIMPLE TOOL -WHEEL AND AXLE - THE GREATEST USE OF THE WHEEL IS WHAT?: TO REDUCE FRICTION
IDEAL MECHANICAL ADVANTAGE OF A SCREW =: DISTANCE TO COMPLETE 1 TURN
____________________________

DISTANCE BETWEEN 2 THREADS
EXAMPLES OF CLASS ONE LEVERS INCLUDE:: -SEESAW
-BALANCE SCALE
-BOAT OAR
-PLIERS
-SCISSORS
WHAT ARE THE 2 PARTS TO A LEVER?: -A BAR
-A FULCRUM
IN A CLASS TWO LEVER, THE EFFORT AND THE LOAD MOVE IN WHAT DIRECTION? (OPPOSITE OR SAME DIRECTION): SAME DIRECTION
FRICTION (HELPS OR HURTS)SCREWS TO DO THEIR WORK.: HELPS
WHERE IS THE FULCRUM ON A CLASS TWO LEVER?: ALWAYS ON ONE END
THE DISTANCE BETWEEN THE THREADS OF A SCREW ARE CALLED?: THE PITCH
EXAMPLES OF CLASS THREE LEVERS INCLUDE:: -RAKE
-FISHING POLE
-TWEEZER
-HAMMER HITTING A NAIL
A SCREW IS A SIMPLE TOOL MADE FROM:: AN INCLINED PLANE WRAPPED AROUND A CYLINDER
EXAMPLES OF CLASS TWO LEVERS INCLUDE:: -NUTCRACKER
-WHEELBARROW
-PAPER CUTTER
-BOTTLE OPENER
WHEN A DRIVE WHEEL GEAR TURNS IT CAUSES WHAT?: IT CAUSES THE GEAR NEXT TO IT TO TURN
A PULLEY IS A SIMPLE TOOL. IT CAN BE DESCRIBED AS:: A WHEEL WITH A ROPE THAT RUNS ALONG THE GROOVE OF THE WHEEL
EXPLAIN RACK AND PINION GEARS: THEY HAVE ONE WHEEL AND A RACK WITH TEETH. THEY MOVE BACK AND FORTH INSTEAD OF AROUND
EXAMPLES OF FIXED PULLEYS INCLUDE:: -RAISING CURTAINS
-RAISING BLINDS
-RAISING SAILS
ANOTHER NAME FOR THE COMPOUND PULLEY IS WHAT?: A BLOCK AND TACKLE
IN A CLASS ONE LEVER, IF THE FULCRUM IN MOVED CLOSER TO THE LOAD, OR THE LOAD MOVES CLOSER TO THE FULCRUM WHAT HAPPENS TO THE AMOUNT OF FORCE?: THE AMOUNT OF FORCE NEEDED TO LIFT THE LOAD IS DECREASED
EXPLAIN SPUR GEARS: THEY ARE ROUND, LIE NEXT TO EACH OTHER, MAGNIFY FORCE, REVERSE DIRECTION
WHEEL AND AXLE - THE TURNING OF THE WHEEL IS THE:: INPUT FORCE
EXPLAIN BEVEL GEARS: THEY COME TOGETHER AT AN ANGLE, CHANGING FORCE AND DIRECTION
WHAT IS A CRANK?: IT IS A WHEEL WITH A ROD ATTACHED TO IT. THE OTHER END OF THE ROD IS HINGED SO THAT THE ROD MOVES BACKWARDS AND FORWARD AS THE WHEEL MOVES
GEARS: DRIVE WHEELS CAN MAKE SMALLER WHEELS TURN _____: FASTER (THEY CAN MAKE LARGER WHEELS TURN SLOWER)
THE TEETH OF THE GEARS ARE CALLED?: COGS
GEARS ARE __________________: WHEELS WITH TEETH ALONG THE OUTER EDGE
