1. A number that tells how many times a machine multiplies force.

2. A device that helps do work by either overcoming a force or changing the direction of the applied force

3. A simple machine consisting of two circular objects of different sizes; the wheel is the larger of the two circular objects

4. The work done on a machine; the product of the input force and the distance through which the force is exerted

5. A simple machine that is made up of two inclined planes and that moves; often used for cutting

6. The unit used to express energy; equivalent to the amount of work done by a force of 1 N acting through a distance of 1 m in the direction of the force

7. A simple machine that consists of a wheel over which a rope - chain - or wire passes

8. The transfer of energy to an object by using a force that causes the object to move in the direction of the force

9. A machine made of more than one simple machine

10. A type of simple machine that consists of an inclined plane wrapped around a cylinder

11. The rate at which work is done or energy is transformed

12. The work done by a machine; the product of the output force and the distance through which the force is exerted

13. The unit used to express power; equivalent to joules per second

14. A simple machine that is a straight - slanted surface - which facilitates the raising of loads; a ramp

15. Simple machine consisting of a bar free to pivot about a fixed point called the fulcrum.

16. A quantity - usually expressed as a percentage - that measures the ratio of work output to work input; it can be calculated by dividing work output by work input.
