Simple Machines
Across
- 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
Down
- 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
