1 LEVERS AND PULLEYS Simple Machines

2 LEVERS: A BEAM, FREE TO PIVOT AROUND A POINT, USED TO MOVE A LOAD.

3 PULLEY: A WHEEL WITH A GROOVED RIM IN WHICH A ROPE CAN RUN TO CHANGE THE DIRECTION OF THE PULL AND SO LIFT A LOAD.

4 LOAD: THE WEIGHT OR RESISTANCE THAT IS MOVED USING A SIMPLE MACHINE.

5 EFFORT: THE FORCE APPLIED TO MOVE A LOAD USING A SIMPLE MACHINE.

6 NEWTON: THE METRIC UNIT USED TO MEASURE FORCE.

7 ADVANTAGE: A GAIN IN EFFORT OR DISTANCE OR A CHANGE OF DIRECTION RESULTING FROM THE USE OF A SIMPLE MACHINE.
