Simple Machines

5. are two or more simple machines that they function together to make work easier.
7. is when you wrap a rope or cable over a grooved wheel. They can change the direction of force and the amount of force required to lift a load.
8. is the transfer of energy from one physical system to another.
9. is a sloping surface that alters the force required to move the load in a perpendicular direction.
11. is used to push two objects apart. It is made with two inclined planes that form a sharp edge to split things apart.

1. is gaining increased force or extended motion by means of machine.
2. is the point in which a lever pivots.
3. is a basic device used to make work easier.
4. is one of a set of toothed wheels that work together to alter the relation between the speed of a driving mechanism (such as the crank of a bicycle) and the speed of the driven parts (the wheels).
6. is an inclined plane wrapped around a cylinder.
8. is a rotating lever (the wheel) that moves around a fulcrum (the axle).
10. converts movement from one side of the fulcrum to movement in the opposite direction on the other side of the fulcrum.
