Simple Machines

2. force exerted on an object that causes it to move
4. simple machine that consist of a rope/cable that is wrapped around a grooved wheel
7. fixed point around which a lever pivots
9. simple machine that is an inclined plane that moves
10. and axle simple machine made of two circular/cylindered objects that are fastned together and that rotate about a common axis
11. work done on a machine as the input force acts through the input distance
13. a device that changes the amount of force exerted, the distance over which a force exerted or the direction in which force is exerted
14. simple machine that consist of a rigid bar that pivots about a fixed point
16. advantage number of times a machine increases a force exerted on it

1. unit of work equal to one newton/meter
3. work done by a machine as the output force acts through the output distance
5. machine a machine that utilizes two or more simple machines
6. plane simple machine that is a flat, slopped surface
8. rate at which work is done
12. simple machine that is an inclined plane wrapped around s central cylinder to form a spiral
15. percentage of the input work that is converted to output work
